Description

Technical Field

[0002] In traditional computing models, such as the von Neumann architecture, storage and computing are physically separated. When using this computing model for data processing, data is frequently transmitted between storage devices and computing devices, resulting in data transmission delays and energy consumption. With the development of technologies such as big data and artificial intelligence, the amount of data processing has increased rapidly, and the demand for data transmission has also increased rapidly. The resulting transmission delays and energy consumption have become increasingly prominent, restricting the development of data processing capabilities, making it difficult for traditional computing models to meet the needs of processing capabilities.

This physical integration includes, for example, the close integration of storage and computing parts through packaging and other processes; for another example, integrating a processing circuit with processing capabilities in the memory to achieve the integration of processing functions in the memory; for another example, using a storage device to implement computing or storing data in a computing device to achieve close integration of storage and computing.

[0049] As an example, Figure 2 A schematic diagram of another storage and computing system according to an exemplary embodiment of the present application is shown.

[0050] like Figure 2 As shown, the storage computing system 200 includes one or more storage cell arrays 210. The storage cell array 210 includes a plurality of storage cells S ij , where i∈[1,m], j∈[1,n], m is the number of rows in the storage cell array, and n is the number of columns in the storage cell array. ij Can store weight data W ij When the memory cell array 210 is in a programming state, the memory cell S ij The conduction capacity of the storage cell array 210 can be controlled based on the weight data to achieve the target state, thereby achieving the storage of the weight data. ij The input terminal IN is connected to the storage unit S ij Provide an input signal, such as an input voltage V i ; Storage unit S ij The output signal, such as output current, is output at the output terminal OUT. 1j -S mj ) can be outputted in a collinear manner. According to Kirchhoff's law, the output signals of multiple storage units are accumulated, and the output signal I j Satisfies the following formula:

[0051]

[0052] In some possible embodiments, the input data includes a digital input signal, and the input signal Vi of the storage cell array 210 may include an analog signal. The input circuit 230 may include, for example, a digital to analog converter (DAC) to convert the digital signal into an analog signal and provide it to the storage cell array 210. In some possible embodiments, the input signal of the storage cell array 210 may include a digital signal, which is represented by the waveform characteristics of the signal, such as the pulse width, amplitude or area of ​​the signal. The input circuit 230 may adjust the waveform of the signal based on the input data to obtain the input signal and provide it to the storage cell array 210.

[0053] In some possible embodiments, the output circuit 240 may include at least one conversion circuit for converting the output signal of the storage cell array 210 and outputting it to the subsequent circuit.

For another example, the output circuit 240 may include a second conversion circuit 242. The second conversion may be implemented, for example, by a sampling circuit.

For another example, the output circuit may include a sense amplifier (SA), which may sense and amplify the signal obtained from the memory cell array 210 or the first conversion circuit 241. Figure 2 In the example, the storage computing system 200 may further include a control circuit 220, which may be used to control the storage cells S in the storage cell array 210. ij operating states, such as the programming state and computing state described above.

[0054] Figure 2 As an example only, a connection method of the memory cells in the memory cell array 210 is shown. Figure 2In addition to the connection methods shown, other connection methods can also be used. For example, the input ends of the storage cells are connected in columns, and the output ends of the storage cells are connected in rows. For another example, the input end of the storage cell may include the gate of a transistor storage device, or the input end of the storage cell may include the source or drain of a transistor storage device, which is not limited in the embodiments of the present application.

Optionally, the gate may also be connected to a capacitor to increase the stability and duration of the stored charge.

[0055] Burning is the operation of writing weight data into the storage circuit, and is the main process for the storage circuit to realize in-memory calculation. Unlike the writing of storage data, the writing of weight data has more precise control requirements for the burning result. In order to achieve more precise burning control, the control circuit controls the writing of weight data through multiple iterations in the programming state of the storage circuit. Each iteration includes the physical execution control of the writing of weight data and the calculation of the next burning control instruction. In this way, the burning process consumes a lot of computing power of the storage and computing system for burning control.

[0056] In view of this, the embodiments of the present application provide a burning method, device and system, which can separate the physical execution and control of burning, reduce the burning control requirements for the storage and computing system, and reduce the computing power requirements of the burning control part of the storage and computing system, so as to reduce the complexity and cost of the storage and computing system. In addition, the burning method has high flexibility, which can reduce the customization requirements for the burning control part of the storage and computing system, so that the storage and computing system can meet the flexibility requirements of writing different weighted data when used for calculations in different business scenarios.

[0057] Figure 3 FIG. 2 shows an architecture diagram of a burning system according to an exemplary embodiment of the present application. Figure 3 As shown, the burning system 300 includes a storage and computing device 310 and a server 320. The storage and computing device 310 can be used for the physical execution of burning, and the server 320 can be used to generate burning control instructions; through the burning control calculation of the server 320, the control requirements for the storage and computing device 310 are reduced, so that the control part of the storage and computing device 310 can release more space or computing power for the control of business calculations.

[0058] like Figure 3 As shown, the server 320 is used to generate a burning instruction and send the burning instruction to the storage and calculation device 310. The storage and calculation device 310 performs a burning operation based on the received burning instruction and reads the burning result. The storage and calculation device 310 sends the burning result to the server 320. The server 320 determines the current burning state based on the obtained burning result, and performs burning calculation in combination with the burning target to obtain the burning instruction. The burning instruction is used to control the next burning operation so that the burning result tends to the burning target. The above process is repeated for many times. When the burning result shows that the current burning state reaches the burning target, the burning operation of the current storage unit can be realized, and the burning operation of other storage units can be continued. In one burning operation, the burning control of one or more storage units can be performed, and the embodiment of the present application is not limited.

[0059] The storage and computing device 310 and the server 320 can be connected to each other by wired or wireless communication. Wired communication methods include, but are not limited to, communication methods based on optical fiber or cable. Wireless communication methods include, but are not limited to, cellular communication (e.g., 3G, 4G, 5G, or 6G), wireless sensor communication (e.g., Bluetooth, Starflash, or ZigBee), wireless local area network communication (e.g., WLAN, or WiFi), short-range point-to-point communication, or near field communication (NFC), etc.

[0060] The application does not limit the form of the server 320, which may include a server, a cloud server, a cloud virtual machine, or a burning device, etc. Using the server 320 for burning control can utilize the rich resources of the server to achieve an optimized layout of the control algorithm. For example, a cloud server or a cloud virtual machine can provide more resources to support flexible control of burning.

[0061] Figure 4 FIG. 1 is a flowchart of a method for burning data according to an exemplary embodiment of the present application. The method may be executed by the storage and computing device 310. Figure 4 As shown, the method includes:

[0062] S410, receiving a first burning instruction from a server, where the first burning instruction includes a first burning parameter;

[0063] S420, controlling a first write according to a first programming parameter, the first write being used to write first weight data into a storage circuit;

[0064] S430, obtaining a first result of the first writing;

[0065] S440, sending a first indication message to the server, where the first indication message is used to indicate a first result;

[0066] S450, receiving a second burning instruction from the server, where the second burning instruction is generated based on the first result and includes a second burning parameter;

[0067] S460: Control a second writing according to the second programming parameter, where the second writing is used to adjust the first weight data written into the storage circuit.

[0068] Figure 5 FIG. 2 shows a flow chart of another burning method according to an exemplary embodiment of the present application. The method can be executed by the server 320. Figure 5 As shown, the method includes:

[0069] S510, sending a first burning instruction to the storage and computing device, the first burning instruction including a first burning parameter, the first burning parameter is used to control a first writing, the first writing is used to write first weight data into the storage circuit;

[0070] S520, receiving a first indication message from a storage and computing device, where the first indication message is used to indicate a first result of the first writing;

[0071] S530, generating a second burning instruction according to the first result, where the second burning instruction includes a second burning parameter;

[0072] S540: Send a second burning instruction to the storage and computing device.

[0073] In the above burning scheme, the physical execution and control calculation of burning are separated and completed on different devices. The physical execution part of burning can be run on the storage and computing device, and the burning control part can be run on a server device different from the storage and computing device. The burning result can be sent to the server device for calculation of the next burning iteration to generate a burning instruction. In this way, the physical execution and control of burning can be separated, the burning control requirements for the storage and computing device are reduced, and the computing power requirements of the burning control part of the storage and computing device are reduced, so that the complexity and cost of the storage and computing device are reduced. In addition, the burning method has high flexibility, which can reduce the customization requirements for the burning control part of the storage and computing device, so that the storage and computing device can meet the flexibility requirements of writing different weight data when used for calculations in different business scenarios.

[0074] The above burning instructions (such as the first burning instruction or the second burning instruction) can be transmitted in encrypted form. When the storage and computing device is used for artificial intelligence calculations, the weight data can reflect the weight information of at least one network layer of the artificial intelligence model. By separating and controlling the burning process of the weight data, the artificial intelligence model can be protected from being obtained through reverse engineering and other means. In addition, through encrypted transmission, the security of the burning control can be further enhanced to prevent malicious attacks.

[0075] The present application does not limit the content of the programming parameters, as long as the storage and calculation device can determine the control signal based on the programming parameters, and the control signal is used to control the writing of the weight data. For example, the programming parameters may include one or more parameters such as the amplitude, pulse width, area, or duration of the control signal. The programming parameters may affect the charge injected into the storage unit, etc., which can be used to reflect the physical characteristics of the weight data, thereby controlling the writing of the weight data through the control signal input. According to some embodiments, the programming parameters (such as the first programming parameters or the second programming parameters) may include, but are not limited to, the above one or more parameters of the control signal. According to some embodiments, the programming parameters may include a control parameter, which may be used to indicate the adjustment range or adjustment size of the control signal parameter, and the control signal may be adjusted to a target range or size based on the control parameter.

[0076] The present application also does not limit the content of the result of writing. Depending on the type of storage circuit, the result may have different content. The result may include signal parameters related to weight data, such as threshold voltage, node voltage, or read current.

[0077] Combined with reference Figure 3 , the server 320 may generate a programming instruction according to the result of the current programming (e.g., the first result) and may include: determining a programming parameter (e.g., a second programming parameter) according to the result of the current programming and the programming target. The present application also does not limit the content of the programming target. The programming target may correspond to the result, for example, including a target range of a threshold voltage, a node voltage, or a read current. For example, the server may determine the gap between the result of the current programming and the target based on the result of the current programming and the programming target, convert the gap into a programming parameter, and provide it to the storage and calculation device 310. The storage and calculation device 310 may input a control signal to the storage circuit based on the programming parameter to control the writing of the weight data to approach the target.

[0078] The storage circuit may include multiple storage units, and the burning of the storage units may be performed independently, or the burning of some storage units may be performed in parallel. According to some embodiments, the server may indicate the storage unit or storage unit set to be burned in the burning instruction.

[0079] According to some embodiments, the storage unit or storage unit set to be programmed may be indicated by address information. For example, the above programming instruction (e.g., the first programming instruction or the second programming instruction) may include address information. The address information is used to indicate the storage unit or storage unit set to be programmed in the storage circuit.

[0080] In this way, the generation of burning instructions can be simplified, and the number of storage units to be burned can be flexibly supported. For example, an instruction template can be set, and the server can modify the address field in the burning instruction according to the address of the storage unit to be burned; according to the current written result, the burning parameter setting is modified. In addition, the burning instruction can realize the indication of the storage unit to be burned through a relatively simple field setting, saving communication resources.

[0081] According to some embodiments, the storage unit or storage unit set to be burned can be indicated by address information and identification information. The above burning instruction (for example, the first burning instruction or the second burning instruction) may include address information and identification information, and the address information and identification information are set accordingly. The address information is used to indicate the storage unit or storage unit set in the storage circuit; the identification information is used to indicate the state of the corresponding storage unit or storage unit set to be burned.

[0082] In this way, the identification information field of whether the storage unit in the range is to be programmed can be updated according to the range of parallel programmable storage units supported by the programming instruction and the address of the currently programmed storage unit, which can simplify the generation process of programming instructions within the range of parallel programmable storage units and improve programming efficiency.

[0083] According to some embodiments, the burning order of the storage unit or storage unit set in the storage circuit can be preset, and the storage and computing device and the server have the same setting for the burning order. When the storage and computing device receives a burning instruction or a burning start instruction, it can write based on the preset burning order. In this way, the transmission of address information or identification information can be omitted, saving transmission resources.

[0084] The above burning method can be applied to the initialization burning of the storage and computing device; it can also be applied to the update of weight data during the use of the storage and computing device, which can simplify the cost and efficiency of weight data update, and the weight data update can be achieved through remote control.

[0085] According to some embodiments, the above burning method may further include: the server sends a burning start instruction to the storage and computing device. Correspondingly, the storage and computing device receives the burning start instruction from the server; according to the burning start instruction, erases all or part of the storage area of ​​the storage circuit.

[0086] The burn start instruction can be used to instruct the storage and computing device to start the burning of the storage circuit. Optionally, the burn start instruction can be used only to start the burning of the storage circuit, so that the storage circuit is ready based on the burn start instruction, such as erasing all or part of the storage area. Optionally, the burn start instruction can be similar to the above burn instruction, carrying the burn parameters, and the storage and computing device can input the control signal for writing the weight data based on the burn instruction. Optionally, the burn start instruction can also include indication information of the storage area (for example, a storage unit or a storage unit set) to be burned in the storage circuit, such as address information, address information and identification information, etc.

[0087] After receiving the programming start instruction, the storage and computing device can erase the storage area to be programmed in the storage circuit indicated by the programming start instruction to prepare for the subsequent programming of the storage and computing unit.

[0088] After receiving the first burning instruction from the server, the storage and computing device can perform a first write according to the first burning parameter in the first burning instruction, and write the first weight data into the storage circuit. The storage and computing device can read or sense the first result of the first write, and indicate the first result to the server through an indication message.

[0089] According to some embodiments, the indication message (e.g., the first indication message) may include first indication information and second indication information, wherein the first indication information is used to indicate the first result, and the second indication information is used to indicate the storage unit or storage unit set corresponding to the first result. According to some other embodiments, the storage and computing device performs burning control according to a preset burning sequence, in which case the indication message may not carry the second indication information.

[0090] The first writing may include writing to all or part of the storage cells in the storage area to be burned in the storage and computing array, and the second indication information may indicate the storage cell or storage cell set corresponding to the first result of the first writing.

[0091] The server obtains the first indication message, and can determine the first result of the first writing based on the first indication message, and generate the second burning instruction based on the first result. The storage units indicated by the first burning instruction and the second burning instruction can be the same or different, for example, the address information in the first burning instruction and the second burning instruction can be the same or different, or the identification information in the first burning instruction and the second burning instruction can be the same or different. For example, none of the storage units in the current storage unit set to be burned has completed burning, the address information in the first burning instruction can be the same as the address information in the second burning instruction, or the address information in the first burning instruction can be the same as the address information and identification information in the second burning instruction; for another example, some of the storage units in the current storage unit set to be burned have completed burning, the address information in the first burning instruction can be different from the address information in the second burning instruction, for example, the second burning instruction may not include the address information of the storage unit that has completed burning; or the address information in the first burning instruction can be the same as the address information in the second burning instruction, and the identification information is different, for example, the identification information of the storage unit that has completed burning in the second burning instruction shows that burning is completed.

[0092] The above programming method can use the server to perform iterative programming control during the programming process of the storage circuit to accurately control the programming result.

[0093] According to some embodiments, the storage unit of the storage circuit can be divided into multiple storage unit sets that can be burned in parallel, thereby improving the burning efficiency. Moreover, during the burning control process, there is a certain transmission delay in the communication between the server and the storage and computing device. Parallel burning can be performed during the transmission waiting process of a storage unit set, thereby reducing the impact of the transmission delay and improving the burning efficiency.

[0094] For example, according to some embodiments, the storage circuit may include multiple storage unit sets, the start times of the programming cycles of the multiple storage unit sets are different, and there is an overlapping time period in the programming cycles. For example, the multiple storage unit sets include a first storage unit set and a second storage unit set, the start times of the programming cycles of the first storage unit set and the second storage unit set are different, and there is an overlapping time period.

[0095] The first storage unit set and the second storage unit set are only used to illustrate the division and set programming of the storage unit set, and do not mean that the storage unit set of the storage circuit can only be divided into two storage unit sets.

[0096] According to some embodiments, the storage units in the same storage unit set have the same programming parameter settings. Dividing the storage units with the same programming parameters into the same storage unit set can simplify the configuration of the programming parameters and improve the programming efficiency.

[0097] During the programming process, some storage units may disturb each other. Dividing the storage units that may disturb each other into different storage unit sets can prevent the programming of the next storage unit set from causing a large disturbance to the previous storage unit set when the previous storage unit set has reached the programming target and the programming is finished, causing the programming result of the previous storage unit set to deviate greatly from the target value.

[0098] For example, according to some embodiments, the storage units in the same storage unit set have independent signal terminals. The storage units with independent signal terminals are divided into the same storage unit set, which can reduce the influence of mutual interference between each other during the burning process. The signal terminal includes, for example, a signal terminal for inputting a control signal when writing weight data, or a signal terminal for inputting an input signal during calculation, or a signal terminal for reading an output signal, etc.

[0099] According to some embodiments, the division of the storage unit set can be determined based on one or more of the following factors: the physical location of the storage unit of the storage circuit, the connection mode of the storage unit of the storage circuit, the transmission delay, and the interference between the storage units. For example, the storage units whose physical locations are more than a preset range apart are divided into the same storage unit set, which can reduce the influence of the mutual disturbance between the storage units on the burning; for another example, according to the connection mode between the storage units, the storage units that are not co-linear or co-terminal connected are divided into the same storage unit set, which can reduce the influence of the mutual disturbance between the storage units on the burning; for another example, according to the interference between the storage units, the storage units whose interference is less than the preset range are divided into the same storage unit set, which can reduce the influence of the mutual disturbance between the storage units on the burning; for another example, based on the transmission delay, the number of storage unit sets that can be burned in parallel is determined. The transmission delay may include a two-way delay or a one-way delay for the communication between the storage and computing device and the server, which is not limited by the embodiments of the present application.

[0100] The division of the storage unit set of the storage circuit can be performed in a static or dynamic manner. In the static division method, the storage units of the storage unit set do not change due to the current burning state, and the storage units in the storage unit set that have completed or not completed the burning can be indicated by identification information; when the burning of all storage units in the storage unit set is completed, the burning of the storage unit set is completed. In the dynamic division method, the storage units in the storage unit set can change, for example, according to the current burning state of the storage circuit, the storage units that have not completed the burning are divided into multiple storage unit sets, and as the burning state of the storage circuit changes, the division of the storage unit set can be dynamically adjusted. In this way, the burning efficiency of the storage circuit can be further improved.

[0101] According to some embodiments, the server may divide the storage units that have not been programmed into at least two storage unit sets based on the current programming status of the storage circuit.

[0102] According to some embodiments, the server divides the storage units that have not been burned into at least two storage unit sets based on the current burning state of the storage circuit, including: determining the storage units that have not been burned based on the current burning state of the storage circuit; dividing the storage units that have not been burned into at least two storage unit sets according to one or more of the following factors of the storage units that have not been burned: the physical location of the storage units of the storage circuit, the connection method of the storage units of the storage circuit, the transmission delay, and the interference between the storage units, etc.

[0103] According to some embodiments, pipeline burning can be performed between storage unit sets to further improve burning efficiency and reduce the impact of transmission delay. For example, during the burning process of the first storage unit set, during the transmission time between the server and the storage and computing device, the second storage unit set can perform burning operations. For example, the server can generate calculations for the burning instructions for the second storage unit set, and the storage and computing device can perform physical execution control of the burning of the second storage unit set; in this way, the transmission delay during the burning process can be concealed, and within the macro time period, the storage and computing device can be kept in a burning state, thereby improving the burning efficiency.

[0104] For example, Figure 6 The schematic diagram of the process of parallel programming of a storage unit set in an exemplary embodiment of the present application is shown. The programming process of the storage unit set may include a physical writing process ( Figure 6 The communication process between the server and the storage device ( Figure 6 The server calculates the writing result and obtains the burning instruction process ( Figure 6 The communication process may include the transmission of a burning instruction or the transmission of an indication message, etc. Figure 6 It can be seen that during the transmission of the storage unit set 1, the storage unit set 2 can be programmed or calculated, thereby making full use of the transmission delay and improving the programming efficiency.

[0105] According to some embodiments, the size of the storage unit set may be determined according to the transmission delay, so that the storage unit set can fully utilize the transmission delay and further improve the burning efficiency.

[0106] Taking the burning process of the first storage unit set and the second storage unit set as an example, according to some embodiments, the above first burning instruction and the second burning instruction are used to write the first weight data to the first storage unit set. Figure 4The burning method shown may also include: receiving a third burning instruction from the server, the third burning instruction including a third burning parameter; controlling a third write according to the third burning parameter, the third write being used to write second weight data to the second storage unit set; obtaining a third result of the third write; sending a third indication message to the server, the third indication message being used to indicate the third result; receiving a fourth burning instruction from the server, the fourth burning instruction being generated based on the third result and including a fourth burning parameter; controlling a fourth write according to the fourth burning parameter, the fourth write being used to adjust the second weight data written to the second storage unit set.

[0107] Accordingly, the above Figure 5 The burning method shown also includes: sending a third burning instruction to the storage and computing device, the third burning instruction includes a third burning parameter, the third burning parameter is used to control the third writing, and the third writing is used to write the second weight data to the second storage unit set; receiving a third indication message from the storage and computing device, the third indication message is used to indicate a third result of the third writing; generating a fourth burning instruction based on the third result, the fourth burning instruction includes a fourth burning parameter, the fourth burning parameter is used to control the fourth writing, and the fourth writing is used to adjust the second weight data written to the second storage unit set; sending the fourth burning instruction to the storage and computing device.

[0108] According to some embodiments, the server may notify the storage and computing device that the burning is finished when the result of the writing reaches the burning target. For example, taking the second result of the second writing reaching the burning target as an example, the above burning method also includes: the storage and computing device obtains the second result of the second writing; sends a second indication message to the server, and the second indication message is used to indicate the second result; receives a burning end instruction from the server, and the burning end instruction is generated based on the second result. Correspondingly, the server receives the second indication message, generates a burning end instruction based on the second result in the second indication message, and sends the burning end instruction to the storage and computing device. For example, when the server determines that the current burning state has reached the burning target based on the second result, it generates a burning end instruction.

[0109] The burning process in this embodiment is an iterative process. The first burning instruction, the second burning instruction, the first burning parameter, the second burning parameter, the first writing, the second writing, the first result, the second result, etc. in this embodiment do not refer to the order and may include any two adjacent burning processes in the burning process.

[0110] During the iteration process, the server can determine whether the burning target is reached according to the current written result. If the burning target is reached, a burning end instruction is generated; if the burning target is not reached, the next round of burning process continues.

[0111] The embodiment of the present application also provides a burning device, which can be located in the storage and computing device, for example, integrated into the control circuit part of the storage and computing system or independent of the control circuit.
