[0002] Currently, flash memory can still retain the stored data information even when powered off, and it is a non-volatile memory. Flash memory has the characteristics of not requiring special high voltages during electrical erasure and repeated programming, low manufacturing cost, and large storage density. It has become the mainstream of non-volatile semiconductor storage technology and is widely used in various fields such as consumer products, industrial equipment, and automotive devices.

[0048] To be able to more clearly understand the above objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0049] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0050] Referring to Figure 1 , it shows that an instruction receiving module of a flash memory device receives a data reading instruction on a data transmission line and controls a data output module to output data to a host device (i.e., Master) through the data transmission line. Figure 2 What is shown is a timing schematic type of data interaction between a flash memory device and a host device under normal circumstances.

[0051] Compared with Figure 2 , as Figure 3 shown, the host device samples the data output by the flash memory device using the rising edge of its own clock signal SCLK_Master to obtain the target read data. Due to the influence of the delay of the transmission path, the data transmitted from the flash memory device to the data receiving port MISO_Master of the host device will be delayed. If the path transmission delay causes the valid data received by the data receiving port MISO_Master of the host device to be later than the rising edge of the sampling clock signal SCLK_Master of the host device, it will cause the host device to sample incorrect data, that is, the host device reads incorrect data.

[0052] It can be seen that Figure 1 in the process of data transmission of the flash memory device shown, after the flash memory device receives a data read command, it passively outputs data to the host device through the data transmission line. For different hardware environments and different working environments, the path delay and signal integrity during the data transmission process will have a great impact on the target data sampled by the host device. If the output transmission delay and signal integrity problems under different working conditions are not adjusted specifically, incorrect data will be sampled by the host device under some conditions, thereby affecting the stability and reliability of the system product.

[0053] In view of the diversification of the application environment or working environment of the flash memory device, the embodiments of the present disclosure provide an adaptive data transmission method, so that the adaptive function of the flash memory device can achieve feedback for adapting to the working environment, and at the same time can achieve real-time adjustment of adaptive configuration parameters, enabling the flash memory device to more reliably and stably achieve data output under different working environments, greatly enhancing the versatility and stability of the system product. For ease of understanding, the embodiments of the present disclosure are described in detail below.

[0054] In this embodiment, an adaptive data transmission method may be provided; this method is applied to a flash memory device that performs data transmission with a host device. Among them, as Figure 4As shown, the main device of the system product transfers data with the flash memory device. The flash memory device may include: a signal detection and control module, an adaptive signal feedback module, a data output parameter configuration module, and a data output control module. In addition, the flash memory device may further include an instruction receiving module.

[0055] In the flash memory device, the signal detection and control module is respectively connected to the main device, the adaptive signal feedback module, the data output parameter configuration module, and the instruction receiving module. The adaptive signal feedback module is connected to the main device. The data output control module is respectively connected to the data output parameter configuration module and the instruction receiving module. The instruction receiving module is connected to the main device.

[0056] Based on the above flash memory device, Figure 5 is a flowchart of an adaptive data transmission method provided by an embodiment of the present disclosure. This method is applied to a flash memory device that transfers data with a main device. This method can be executed by an adaptive data transmission device, and this device can be implemented by a flash memory device. As Figure 5 shown, an adaptive data transmission method may include the following steps.

[0057] S102, when the signal detection and control module receives a data reading instruction sent by the main device, it generates a control signal according to the data reading instruction.

[0058] In this embodiment, the signal detection and control module detects the data reading instruction from the main device on the data transmission line. This data reading instruction is, for example, a timing signal of high and low levels. Then, it generates a control signal f_oper according to the data reading instruction.

[0059] Among them, the embodiment in which the signal detection and control module generates a control signal f_oper according to the data reading instruction may include:

[0060] The signal detection and control module determines the data reading method corresponding to the data reading instruction. Among them, the data reading method is used to represent the data reading method of a single data transmission line or multiple data transmission lines;

[0061] Determine the idle time matching the number of data transmission lines in the data reading method;

[0062] Generate a control signal f_oper according to the idle time.

[0063] In specific implementation, the data reading methods of the SPI protocol include single-line reading and multi-line reading. Single-line reading is the data reading method of a single data transmission line, and multi-line reading is the data reading method of multiple data transmission lines. The lengths of the idle times corresponding to different data reading methods are different. To ensure that the control signals are transmitted in a timely manner, release the data transmission lines, and avoid excessive occupation of the data transmission lines, in this case, different control signals need to be determined for different data reading methods.

[0064] Therefore, the signal detection and control module first needs to determine whether the data reading method corresponding to the data reading instruction is single-line reading or multi-line reading, and the number of data transmission lines in the case of multi-line reading. The SPI frame structure of the data reading instruction has a fixed format. Exemplarily, it may include, but is not limited to: 8-bit instruction information and 24-bit address information. Among them, 24-bit address information is used to transmit data. Similarly, when transmitting 24-bit address signals, it takes 24 cycles to complete the transmission in the case of single-line reading, and it takes 6 cycles to complete the transmission in the case of multi-line reading with 4 data transmission lines. Correspondingly, the idle times during the intermediate processes of single-line reading and multi-line reading are different, that is: single-line reading corresponds to 24 cycles, and correspondingly there are 24 idle times, multi-line reading corresponds to 6 cycles, and correspondingly there are 6 idle times.

[0065] Furthermore, a control signal f_oper is generated according to the idle time, thereby ensuring that the control signal f_oper does not occupy the normal data transmission time of the data transmission line.

[0066] The signal detection and control module sends the generated control signal f_oper to the adaptive feedback module.

[0067] S104, the adaptive signal feedback module generates a feedback signal according to the control signal of the signal detection and control module, and sends the feedback signal to the master device, so that the master device generates a data read-back instruction according to the feedback signal.

[0068] In this embodiment, the adaptive signal feedback module performs conversion processing on the control signal f_oper to generate an adaptive feedback signal f_au, and sends the feedback signal f_au to the master device of the system product in the idle state of the data transmission line.

[0069] Among them, the specific process of the adaptive signal feedback module sending the feedback signal to the master device may include:

[0070] The adaptive signal feedback module determines the idle state of the data transmission line between the flash memory device and the master device according to the SPI frame structure of the data reading instruction, and sends the feedback signal to the master device in the idle state of the data transmission line.

[0071] For example, the SPI frame structure of the data read instruction includes, but is not limited to: 8-bit instruction information and 24-bit address information. When the master device inputs 24-bit address information to the flash device, it is equivalent to a redundant period in the middle. During this period, the data transmission line only receives the address information simply, and the flash device does not return any data to the master device. Therefore, it can be considered that the data transmission line is in an idle state when receiving 24-bit address information. Furthermore, the adaptive signal feedback module of the flash device uses the idle state of the data transmission line to send the feedback signal f_au to the master device.

[0072] After receiving the feedback signal f_au, the master device can generate a data read-back instruction f_mback according to the feedback signal f_au.

[0073] In one embodiment, the master device uses clock signals SCLK_Master with different delays to scan and sample the feedback signal f_au to obtain a first sampled feedback signal; uses different edges of the clock signal SCLK_Master to sample the first sampled feedback signal received at the MISO_Master port to obtain a second sampled feedback signal. The above is the process of the master device receiving the feedback signal from the flash device. Next, according to the reception time of the second sampled feedback signal and the transmission time of the data read instruction, a data read-back instruction f_mback is generated.

[0074] The master device can clearly record the time when it initially sent the data read instruction and the time when it currently receives the second sampled feedback signal, calculate the time difference between the reception time of the second sampled feedback signal and the transmission time of the data read instruction, and can determine the delay time generated by the data transmission line in the current working environment and the compensation operations that need to be performed for the generated delay time. Such compensation operations include adjusting the data transmission speed, adjusting the sampling time point, etc.

[0075] Furthermore, the master device generates a data read-back instruction f_mback according to the delay time and the compensation operation, and sends the data read-back instruction f_mback to the signal detection and control module of the flash device. It can be understood that the data read-back instruction in this embodiment is used to instruct the flash device to perform adaptive data transmission with reference to the delay time and compensation operation given by the master device.

[0076] S106, the signal detection and control module generates a transmission control instruction for adjusting data transmission parameters according to the data read-back instruction sent by the master device.

[0077] In this embodiment, the signal detection and control module receives the data read-back instruction f_mback sent by the master device, identifies the delay time and compensation operation included in the data read-back instruction f_mback, and determines the target data transmission parameter to be modified and adjusted according to the delay time and compensation operation; then generates a transmission control instruction f_trim for the target data transmission parameter to be modified and adjusted, and sends the transmission control instruction to the data output parameter configuration module. An example of the transmission control instruction f_trim can be referred to as follows.

[0078] Example 1: Assume that the data transmission time threshold between the master device and the flash memory device is 100 nanoseconds, that is, the time difference between the transmission time of the master device's data read instruction and the reception time of the feedback signal (specifically, the second sampling feedback signal) should be within 100 nanoseconds, but actually it has passed 150 nanoseconds, resulting in a delay time of 50 nanoseconds. In order to control the data transmission speed faster, it can be determined that the compensation operation is to increase the output level threshold. In this case, the signal detection and control module determines the target output level threshold to be modified and adjusted according to the compensation operation. The target output level threshold to be modified and adjusted is, for example, increased by 20% based on the original output level threshold; generates a transmission control instruction f_trim for the output level threshold to be modified and adjusted.

[0079] Example 2: The delay time generated during data transmission between the master device and the flash memory device is relatively large, and it is difficult to ensure the timeliness of transmission through the compensation operation of increasing the output level threshold. At this time, the compensation operation of delaying the sampling time point backward can be adopted. In this case, the signal detection and control module determines the target sampling time point to be modified and adjusted according to the compensation operation, and generates a transmission control instruction f_trim for the target sampling time point to be modified and adjusted.

[0080] Compared with the prior art, the flash memory device in this embodiment does not directly perform data transmission on the data read instruction of the master device, but sends a feedback signal to the master device through the signal detection and control module and the adaptive signal feedback module. Through the feedback signal, the master device determines the delay time and compensation operation generated by the data transmission line in the current working environment. Then, the flash memory device will generate a transmission control instruction for adjusting the data transmission parameter according to the data read-back instruction, that is, the flash memory device will perform data transmission according to the adaptively adjusted data read-back instruction, thereby ensuring the stability and reliability of data output, and greatly enhancing the versatility and stability of the system product. At the same time, the above adaptive data transmission process does not require any external intervention and can be achieved through the collaborative work of different modules inside the flash memory device.

[0081] S108, the data output parameter configuration module adjusts and controls the current data transmission parameter according to the transmission control instruction of the signal detection and control module to obtain the target data transmission parameter.

[0082] In this embodiment, the data output parameter configuration module adjusts and controls the current data transmission parameters according to the transmission control instruction, specifically by adjusting the current data transmission parameters to the target data transmission parameters Output_control_code indicated by the transmission control instruction.

[0083] S110. The data output control module transmits the target data corresponding to the data read instruction to the host device according to the target data transmission parameters.

[0084] Based on the above embodiments, the flash memory device provided in this embodiment may further include: an instruction receiving module respectively connected to the signal detection control module, the host device, and the data output control module; correspondingly, the adaptive data transmission method may further include:

[0085] When the instruction receiving module receives the data read instruction sent by the host device, it controls the data output control module to transmit the target data corresponding to the data read instruction to the host device.

[0086] In this embodiment, the instruction receiving module controls the data output control module to transmit the target data to the host device to prevent the flash memory from being unable to transmit data to the host device when other modules fail.

[0087] In summary, the adaptive data transmission method provided in the embodiments of the present disclosure is applied to a flash memory device for data transmission with a host device. The flash memory device includes: a signal detection control module, an adaptive signal feedback module, a data output parameter configuration module, and a data output control module; the method includes: when the signal detection control module receives the data read instruction sent by the host device, it generates a control signal according to the data read instruction; the adaptive signal feedback module generates a feedback signal according to the control signal of the signal detection control module and sends the feedback signal to the host device so that the host device generates a data read-back instruction according to the feedback signal; the signal detection control module generates a transmission control instruction for adjusting the data transmission parameters according to the data read-back instruction sent by the host device; the data output parameter configuration module adjusts and controls the current data transmission parameters according to the transmission control instruction of the signal detection control module to obtain the target data transmission parameters; the data output control module transmits the target data corresponding to the data read instruction to the host device according to the target data transmission parameters.

[0088] In this technical solution, after the flash memory device receives a read instruction from the host device, it does not directly perform data transmission. Instead, it sends a feedback signal to the host device through the signal detection and control module and the adaptive signal feedback module in the flash memory device, thereby automatically detecting and feedbacking the signal transmission quality, and realizing the detection and feedback adapted to the working environment. Then, the flash memory device will generate a transmission control instruction for adjusting the data transmission parameters according to the data read instruction re-sent by the host device using the feedback signal, and realize the real-time adjustment of the data transmission parameters adapted to the environment through the transmission control instruction, and finally perform data transmission according to the target data transmission parameters after adaptive adjustment. During the above data transmission process, through the collaborative work of each module, this solution can automatically detect, feedback, and adjust the signal transmission quality without external intervention, enabling the flash memory device to more reliably and stably output data in different working environments, greatly enhancing the versatility and stability of the system product.
