[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on November 30, 2023, with application number 202311629028.7, and application name “A memory capacity adjustment method, device, electronic device and storage medium”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of memory adjustment technology, and in particular to a memory capacity adjustment method, device, electronic device, and storage medium. Background Art

[0004] In a computer system, data information usually needs to be stored in memory. Even though some processors support a certain amount of cache, these cache functions only provide basic instruction execution requirements for the processor when it is turned on. Similarly, the BIOS (Basic Input Output System) image also needs to be run in a certain amount of memory space. The self-test program that starts when the server is turned on and the applications running under the system all require a certain amount of memory to support them. Therefore, memory is a physical device that must exist in any computer product of any architecture. The memory in the server operation involves the setting of multiple parameters, such as the memory integrated circuit and module manufacturer, operating frequency, operating voltage, speed, capacity, voltage, row and column address bandwidth, etc. These parameters are all controlled by the memory's SPD (Serial Presence Detect).

[0005] SPD is a type of memory on the memory module that stores its parameters. This information is read and saved to the motherboard controller during computer startup, allowing the system to correctly configure the memory controller. Most importantly, it automatically configures the memory's operating frequency to ensure the memory controller operates within the appropriate frequency range, thereby improving computer performance. Depending on the usage environment, traditional memory may need to be converted from a slot-based format to a motherboard surface-mounted format. This conversion merely changes the memory connection method and does not affect actual use. However, in some special cases or to reduce investment costs, it is necessary to remove the memory's SPD controller, i.e., to eliminate the SPD controller.

[0006] Typically, memory without an SPD controller requires maintenance personnel to remove the memory from the server to adjust the memory capacity. This reduces the memory's lifespan and increases maintenance costs. Furthermore, server manufacturers often use memory from different batches and capacities from the same vendor. However, memory modules themselves contain SPD controllers with unique parameter settings. Without an SPD controller, mixing these memory modules in a server can lead to technical issues such as server startup failures.

[0125] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0126] 1 , a flowchart of a memory capacity adjustment method provided by an embodiment of the present invention is shown. The memory capacity adjustment method can be applied to BIOS. As shown in FIG1 , the memory capacity adjustment method can include: step 101 and step 102 .

[0127] Step 101: Read the SPD data of the reserved target memory from the BIOS image of the BIOS, where the target memory is the physical memory without an SPD controller.

[0128] The embodiments of the present application can be applied to a scenario in which the memory capacity of a memory without an SPD controller is dynamically adjusted.

[0129] The embodiments of the present application can be applied to BIOS, also known as basic input and output system, that is, the execution entity is BIOS.

[0130] In a specific implementation, the memory's SPD data, also known as memory configuration data, can be pre-stored within the BIOS image, eliminating the need for a built-in SPD controller, also known as a memory configuration controller, within the memory. The SPD data storage process is described in detail below with reference to Figure 2.

[0131] 2 , a flowchart of a method for storing SPD data according to an embodiment of the present invention is shown. As shown in FIG2 , the method for storing SPD data may include: step 201 , step 202 , step 203 , and step 204 .

[0132] Step 201: Acquire SPD data of multiple types of memory, where the multiple types of memory include a target memory.

[0133] In this embodiment, when performing SPD data storage, SPD data of multiple types of memories may be acquired, wherein the multiple types of memories may include a target memory.

[0134] In practical applications, the multiple types of memory may include: memories of different models and different memory capacities from different memory manufacturers.

[0135] When storing SPD data, SPD data of various types of memory may be obtained. The SPD data of various types of memory may be SPD data defined by a memory manufacturer when producing the memory.

[0136] After the SPD data of the multiple types of memories are acquired, step 202 is executed.

[0137] Step 202: Create a data structure corresponding to each memory parameter in the BIOS image.

[0138] In this example, a data structure is a data structure used to store data. In the C language, a data structure is a type of aggregate data type. A data structure can be declared as a variable, pointer, or array, to implement complex data structures. A data structure is also a collection of elements, which are called structure members. In this example, SPD data can be stored as a member of a data structure.

[0139] After obtaining the SPD data of multiple types of memory, a data structure corresponding to each memory parameter can be established in the BIOS image. In this example, the SPD data of one memory parameter corresponds to one data structure.

[0140] After the data structure corresponding to each memory parameter is created in the BIOS image, step 203 is executed.

[0141] Step 203: According to the memory parameters of each type of memory, the SPD data of each type of memory is stored in a corresponding data structure.

[0142] After a data structure corresponding to each memory parameter is established in the BIOS image, the memory parameters of each type of memory and the SPD data of each type of memory may be stored in the corresponding data structure.

[0143] Step 204: Store the data structure of each type of memory in the storage address corresponding to each type of memory.

[0144] Furthermore, the data structure of each type of memory can be stored in the storage address corresponding to each type of memory. In a specific implementation, the storage address can be an I2C (Inter-Integrated Circuit) address, each type of memory can correspond to an I2C address, and multiple data structures can be stored in one I2C address. As shown in Figure 12, the SPD address corresponding to memory 0 can include: SPD address A0, SPD address A2, SPD address A4, SPD address A6 under CPU0, and SPD address B0, SPD address B2, SPD address B4, SPD address B6. And SPD address C0, SPD address C2, SPD address C4, SPD address C6 under CPU1, and SPD address D0, SPD address D2, SPD address D4, SPD address D6, etc. The CPU (Central Processing Unit) can read the corresponding SPD data from the SPD address through the I2C protocol.

[0145] The embodiment of the present application stores different types of SPD data in the BIOS image, so that the memory capacity of the memory can be dynamically adjusted even after the SPD controller is removed from the memory.

[0146] In this embodiment, in addition to the SPD data of the memory defined by the memory manufacturer, the user can also set corresponding memory capacity parameters for different memory devices and replace the original memory capacity parameters of the acquired SPD data to generate and store new SPD data. This implementation process is described in detail below with reference to FIG3.

[0147] 3 , a flowchart of another SPD data storage method provided by an embodiment of the present application is shown. As shown in FIG3 , the SPD data storage method may include: step 301 , step 302 , and step 303 .

[0148] Step 301: Obtain the memory capacity parameters of each type of memory set by the user.

[0149] In an embodiment of the present application, after obtaining SPD data of multiple types of memory, the user can set the memory capacity parameters of each type of memory.

[0150] In a specific implementation, the user may set one memory capacity parameter or multiple memory capacity parameters for each type of memory. Specifically, it may be determined according to business needs, and this embodiment does not impose any restrictions on this.

[0151] After the memory capacity parameters of each type of memory set by the user are obtained, step 302 is executed.

[0152] Step 302: replacing the original memory capacity parameter in the SPD data of each type of memory based on the memory capacity parameter to generate new SPD data of each type of memory.

[0153] After the memory capacity parameters of each type of memory set by the user are acquired, the original memory capacity parameters in the SPD data of each type of memory may be replaced based on the memory capacity parameters to generate new SPD data of each type of memory.

[0154] Step 303: Store the SPD data and the new SPD data in corresponding data structures respectively, and different SPD data corresponds to different data structures.

[0155] Furthermore, a data structure corresponding to the new SPD data can be created in the storage address corresponding to each type of memory, and then the SPD data and the new SPD data are respectively stored in the corresponding data structures, and different SPD data corresponds to different data structures.

[0156] In this embodiment, the user can customize the memory capacity parameters of the memory, so that the memory capacity can be adjusted on demand in the future, the physical memory can be set according to the actual needs of the user, and the memory capacity of the server can be dynamically adjusted to meet the actual business needs of the customer.

[0157] After the SPD data is stored, when the target memory is initialized, the reserved SPD data for the target memory can be read from the BIOS image. This target memory is the physical memory without an SPD controller. In a specific implementation, after the BIOS enters the initialization phase, the user can set the memory capacity parameters for the target memory. SPD data matching these memory capacity parameters can then be read from the BIOS image. This implementation process is described in detail below with reference to FIG4 .

[0158] 4 , a flowchart of a method for reading SPD data according to an embodiment of the present invention is shown. As shown in FIG4 , the method for reading SPD data may include: step 401 and step 402 .

[0159] Step 401: After the BIOS enters the initialization phase in response to the server startup, the memory capacity parameter set by the user for the target memory is obtained.

[0160] In an embodiment of the present application, after the server is powered on, the BIOS may start to enter the initialization phase, as shown in Figure 14. After the server is powered on, the BIOS begins to initialize the memory. At this time, the BIOS interface may be displayed, and the user may set the memory capacity parameters for the target memory in the BIOS interface, that is, the user sets the memory capacity required to adjust the target memory.

[0161] After obtaining the memory capacity parameters set by the user for the target memory, step 402 is executed.

[0162] Step 402: Read the SPD data of the target memory that matches the memory capacity parameter from the BIOS image.

[0163] After obtaining the user-set memory capacity parameters for the target memory, the SPD data matching the target memory capacity parameters can be read from the BIOS image. This SPD data contains the user-set memory capacity parameters. As shown in Figure 14, the BIOS can read the memory SPD data via the I2C protocol. First, the BIOS obtains the preset value for the memory capacity option and then reads the BIOS's preset SPD data according to the preset value.

[0164] In the embodiment of the present application, the memory capacity of the target memory can be set according to the actual needs of the user by allowing the user to customize the memory capacity parameters of the target memory, thereby meeting the actual business needs of the user.

[0165] In a specific implementation, when reading SPD data that matches the memory capacity parameter, the storage address corresponding to the target memory can be obtained, and then the corresponding SPD data can be read from the storage address. The implementation process can be described in detail below with reference to FIG5 .

[0166] 5 , there is shown a flowchart of another SPD data reading method provided by an embodiment of the present application. As shown in FIG5 , the SPD data reading method may include: step 501 and step 502 .

[0167] Step 501: Determine a target storage address corresponding to the target memory according to the memory type of the target memory.

[0168] In this embodiment, after obtaining the memory capacity parameters of the target memory set by the user, the target storage address corresponding to the target memory can be determined according to the memory type of the target memory, that is, at least one SPD data of the target memory is stored in the target storage address.

[0169] After determining the target storage address corresponding to the target memory according to the memory type of the target memory, step 502 is executed.

[0170] Step 502: Read SPD data matching the memory capacity parameter from the target storage address based on a preset protocol.

[0171] After determining the target storage address corresponding to the target memory based on the memory type of the target memory, SPD data matching the memory capacity parameters can be read from the target storage address based on a preset protocol. In this example, the target storage address can be an I2C address, and the preset protocol is the I2C protocol. After determining the target storage address, SPD data matching the memory capacity parameters can be read from the I2C address based on the I2C protocol.

[0172] In a specific implementation, after determining the target storage address corresponding to the target memory, the corresponding target data structure can also be determined based on the memory capacity parameter, so that the corresponding SPD data can be read from the target data structure of the target memory. The implementation process can be described in detail below with reference to FIG6.

[0173] 6 , there is shown a flowchart of steps of another SPD data reading method provided by an embodiment of the present application. As shown in FIG6 , the SPD data reading method may include: step 601 and step 602 .

[0174] Step 601: Obtain a target data structure corresponding to a memory capacity parameter.

[0175] In the embodiment of the present application, after obtaining the target memory capacity parameter set by the user, the target data structure corresponding to the memory capacity parameter can be obtained. It is understood that since each type of SPD data corresponds to a corresponding data structure, the BIOS can pre-record this correspondence. Furthermore, after obtaining the target memory capacity parameter set by the user, the target data structure corresponding to the memory capacity parameter can be determined based on this correspondence.

[0176] After the target data structure corresponding to the memory capacity parameter is obtained, step 602 is executed.

[0177] Step 602: Read the SPD data matching the memory capacity parameter in the target data structure from the target storage address based on a preset protocol.

[0178] After obtaining the target data structure corresponding to the memory capacity parameter, the SPD data matching the memory capacity parameter in the target data structure can be read from the target storage address based on a preset protocol.

[0179] The embodiment of the present application sets a corresponding storage address for each memory in advance and designs a corresponding data structure for different SPD data of the memory, so that after obtaining the memory capacity parameters set by the user, the corresponding SPD data can be quickly read, thereby improving the efficiency of data reading and thus improving the efficiency of memory initialization.

[0180] After the SPD data of the reserved target memory is read from the BIOS image of the BIOS, step 102 is executed.

[0181] Step 102: Adjust the memory capacity of the target memory based on the SPD data of the target memory.

[0182] After reading the reserved SPD data of the target memory from the BIOS image of the BIOS, the memory capacity of the target memory can be adjusted based on the SPD data of the target memory. The memory capacity adjustment process can be described in detail below with reference to FIG.

[0183] 7 , there is shown a flowchart of another method for adjusting memory capacity provided by an embodiment of the present application. As shown in FIG7 , the method for adjusting memory capacity may include: step 701 and step 702 .

[0184] Step 701: Assign the SPD data of the target memory to the target memory.

[0185] In this embodiment, after the SPD data of the target memory is read from the BIOS image, the SPD data of the target memory can be assigned to the target memory. As shown in Figure 14, the BIOS can assign the BIOS built-in SPD data to the memory and initialize it.

[0186] Step 702: Initialize the target memory to adjust the memory capacity of the target memory.

[0187] Furthermore, the target memory may be initialized to adjust the memory capacity of the target memory.

[0188] By storing the memory's SPD data in the BIOS image, the present embodiment can directly assign the memory to the memory when the server boots up using the reserved SPD data in the BIOS image. This allows for memory capacity adjustment without an SPD controller, eliminating the need for manual disassembly and adjustment of memory capacity. This avoids the problem of memory lifespan reduction caused by frequent memory removal, reducing operation and maintenance costs. Furthermore, it also avoids the problem of server failure to boot due to memory of different capacities and different batches from the same memory vendor being connected to the server.

[0189] In a specific implementation, after the target memory is initialized, it is also possible to check whether there is any uninitialized memory in the memory of the server to which the BIOS is connected. If there is any uninitialized memory in the memory of the server to which the BIOS is connected, the uninitialized memory can be initialized in sequence. This implementation process can be described in detail below with reference to FIG8.

[0190] 8 , which shows a flow chart of steps of a memory initialization method provided by an embodiment of the present application. As shown in FIG8 , the memory initialization method may include: step 801 , step 802 , and step 803 .

[0191] Step 801: After the target memory is initialized, check whether there is any uninitialized memory in the memory of the server to which the BIOS is connected.

[0192] In the embodiment of the present application, after the target memory is initialized, it is possible to check whether there is any uninitialized memory in the memory of the server to which the BIOS belongs. As shown in Figure 14, after the current memory is initialized, it is possible to determine whether all memory initializations have been completed. If not, the next memory is initialized and the next memory is initialized according to the above-mentioned SPD data reading and assignment process until all memory initializations are completed.

[0193] Step 802: When there is uninitialized memory in the memory, identify the uninitialized memory in the memory in sequence.

[0194] When uninitialized memory exists in the memory of the server to which the BIOS is connected, the uninitialized memory in the memory of the server to which the BIOS is connected can be identified in sequence.

[0195] Step 803: Read the SPD data of the uninitialized memory from the BIOS image in sequence to initialize the uninitialized memory in sequence.

[0196] Furthermore, the SPD data of uninitialized memory can be sequentially read from the BIOS image to initialize the uninitialized memory. For example, if the uninitialized memory includes memory 1, memory 2, and memory 3, then the SPD data of memory 1 can be first read from the BIOS image to assign the value to memory 1 and initialize memory 1. Then, the SPD data of memory 2 can be read from the BIOS image to assign the value to memory 2 and initialize memory 2. Finally, the SPD data of memory 3 can be read from the BIOS image to assign the value to memory 3 and initialize memory 3, etc.

[0197] It can be understood that the above examples are merely examples listed for a better understanding of the technical solutions of the embodiments of the present application, and are not intended to be the sole limitation on the embodiments.

[0198] The embodiment of the present application can complete the initialization of all memories by checking whether all memories have been initialized and performing initialization processing in sequence, thereby avoiding the situation where the computer cannot be started normally due to uninitialized memory.

[0199] In a specific implementation, if all memory in the server is initialized, it can be determined whether the server has booted normally. If so, the memory initialization process ends and the server can be booted normally. If the server does not boot normally, the memory can be reinitialized. This implementation process is described in detail below with reference to Figure 9.

[0200] 9 , there is shown a flowchart of another memory initialization method provided by an embodiment of the present application. As shown in FIG9 , the memory initialization method may include: step 901 and step 902 .

[0201] Step 901: After checking that all memory initialization is complete, determine whether the server is started normally.

[0202] In this embodiment, after checking that all memories of the access server have been initialized, the server continues to start, and the BIOS determines whether the server can start normally.

[0203] If the server is not started normally, execute step 902.

[0204] Step 902: In response to the server not starting normally, reinitialize the memory.

[0205] When it is determined that the server is not started normally, the memory can be reinitialized in response to the server not starting normally, that is, all memories connected to the server are reinitialized.

[0206] In this example, the minimum memory parameters of all memories can be obtained, and all memories can be reinitialized in combination with the SPD data corresponding to the minimum memory parameters. This implementation process can be described in detail below with reference to FIG10.

[0207] 10 , which shows a flowchart of steps of another memory initialization method provided by an embodiment of the present application. As shown in FIG10 , the memory initialization method may include: step 1001 , step 1002 , and step 1003 .

[0208] Step 1001: Obtain a preset minimum memory parameter.

[0209] In this embodiment, when it is determined that the server is not started normally, a preset minimum memory parameter of the memory of the access server may be obtained.

[0210] It can be understood that the minimum memory parameter may be a parameter set by a memory manufacturer when producing the memory.

[0211] After obtaining the preset minimum memory parameter, step 1002 is executed.

[0212] Step 1002: Read target SPD data corresponding to the minimum memory parameter from the BIOS image.

[0213] After obtaining the preset minimum memory parameters of the memory, the target SPD data corresponding to the minimum memory parameters can be read from the BIOS image.

[0214] Step 1003: Assign the target SPD data to the memory and initialize the memory.

[0215] Then, the target SPD data can be assigned to the memory, and the memory can be initialized before the server continues to boot. As shown in Figure 14, if the server boots normally, the memory initialization is complete and the server can boot normally. If the server does not boot normally, it is reinitialized and the minimum capacity of SPD data is loaded.

[0216] The embodiment of the present application can solve the problem that the server cannot start normally after the memory capacity is adjusted by reinitializing the memory according to the SPD data of the minimum memory parameter when the server cannot start normally.

[0217] In a specific implementation, after the memory is reinitialized and the server is started normally, the memory capacity of the memory may not be adjusted, that is, the memory capacity adjustment process is terminated.

[0218] In another specific implementation, after the memory is reinitialized and the server is started normally, the user can set the memory parameters to adjust the memory capacity of the memory. The implementation process can be described in detail below with reference to FIG11.

[0219] 11 , there is shown a flowchart of steps of another memory adjustment method provided by an embodiment of the present application. As shown in FIG11 , the memory adjustment method may include: step 1101 and step 1102 .

[0220] Step 1101: In response to the server starting normally, the SPD data in the memory is read sequentially from the BIOS image.

[0221] In this embodiment, after the memory is reinitialized and the server boots normally, the SPD data of the memory can be sequentially read from the BIOS image in response to the normal server boot. Specifically, the user can re-set the memory capacity parameters of the memory, and then read the SPD data corresponding to the memory capacity parameters from the BIOS image.

[0222] Step 1102: Initialize the memory based on the SPD data of the memory in sequence to adjust the memory capacity of the memory.

[0223] Furthermore, the memory can be initialized based on the SPD data of the memory in sequence to adjust the memory capacity of the memory.

[0224] The embodiment of the present application can achieve dynamic adjustment of memory capacity by adjusting the memory capacity according to SPD data after the server is started.

[0225] The above implementation process can be described in detail as follows in conjunction with FIG13 .

[0226] As shown in Figure 13, after the server boots, BIOS memory initialization begins. First, the BIOS reads the SPD data of the memory I2C address through the I2C protocol. When the BIOS reads the SPD data, it first obtains the memory capacity setting parameters of the memory capacity option on the BIOS interface, that is, the preset value of the memory capacity option. Then, after the BIOS obtains the BIOS option memory parameter setting, it reads the SPD data corresponding to the parameter. After the BIOS obtains the BIOS preset SPD data parameters according to the BIOS option setting, it assigns the parameters to the memory identified at this time and initializes the memory. When the memory module identified by the BIOS has been initialized, the parameters of the next memory are read and initialized. After all memory initialization is completed, the server continues to boot; if the server cannot continue to boot after initialization is completed, the memory is reinitialized and the memory parameters are set to the minimum settings, ignoring the BIOS memory capacity option setting value.

[0227] The memory capacity adjustment method provided in the embodiment of the present application reads the reserved SPD data of the target memory from the BIOS image of the BIOS, where the target memory is the physical memory without an SPD controller. Based on the SPD data of the target memory, the memory capacity of the target memory is adjusted. In the embodiment of the present application, the SPD data of the memory is stored in the BIOS image. When the server starts, it can be directly assigned to the memory through the SPD data reserved in the BIOS image, thereby realizing memory capacity adjustment without an SPD controller. There is no need to manually disassemble and adjust the memory capacity, thereby avoiding the problem of reduced memory life due to frequent memory disassembly and reducing operation and maintenance costs. At the same time, it can also avoid the problem of the server being unable to start up due to the memory of different batches and different capacities of the same memory manufacturer being connected to the server.
