Technical Field
The present invention relates to the field of memories, and in particular, to a data storage method, apparatus, device, and medium.
Background
Currently, there are four general memory modes for Nand flash memory, namely SLC (i.e., single Level Cell, single layer memory Cell) mode, MLC (i.e., mult Level Cell) mode, TLC (i.e., triple Level Cell, triple layer memory Cell) mode, and QLC (i.e., quad Level Cell) mode. Although Nand flash memory has been developed to TLC, i.e., 3 bits of data can be stored in one memory cell, and QLC, i.e., 4 bits of data can be stored in one memory cell; however, in each SSD (Solid State Disk) scheme, in order to ensure that code files stored in a Nand flash memory have better data retention, an SSD master manufacturer generally still uses SLC mode to store firmware codes; however, due to the diversity of development, the ways of entering SLC modes of Nand flash memories of different categories are different, and different entering ways may be used in different periods, so that compatibility with different entering ways is required.
In the general technology, the SSD master manufacturer is compatible with the mode that the Nand flash memory enters the SLC mode by designing a starting code (i.e. a boot code), but the mode selection mode is limited by the compatibility of the boot code, and even if the compatibility of the boot code is continuously improved, the incompatibility condition exists. In addition, since boot codes are usually fixed in the ROM of the chip, in order to improve compatibility with different Nand flash memories, chip resources such as GPIO and OTP are usually used, resulting in resource waste.

Detailed Description
In the prior art, the problem of compatibility of the flash memory in a mode selection mode is solved by improving the compatibility of boot codes, but the mode has limitations, and the compatibility of the flash memory is reduced. In order to overcome the technical problems, the application provides a data storage method based on a flash memory, which can improve the compatibility of the flash memory.
The embodiment of the application discloses a data storage method applied to a flash memory, and referring to fig. 1, the method may include the following steps:
step S11: the target field in the local otp register is read.
In this embodiment, first, a target field preset in a local One-Time programmable (OTP) register is read to perform a relevant configuration operation for a storage mode of the flash memory, and a location of the target field may be set by a flash memory manufacturer according to an actual application situation; the data size of the target field may be 1bit. Therefore, by adding the configuration of a 1bit field aiming at the storage mode in the OTP, a flash memory manufacturer can be convenient to purposefully modify the corresponding configuration in the flash memory packaging test stage.
Step S12: and determining the storage mode type corresponding to the target field.
In this embodiment, after reading the target field in the otp register, the storage mode type corresponding to the configuration is identified based on the target field, where the storage mode type may include a single-layer storage unit mode and a multi-layer storage unit mode.
Step S13: and determining a default storage mode based on the storage mode type, and storing data in the default storage mode.
In this embodiment, after determining the storage mode type, determining a default storage mode according to the determined storage mode type, so that the flash memory performs data storage based on the default storage mode; in this embodiment, the flash memory may be Nandflash. It can be understood that if the storage mode type is a single-layer storage mode, the default storage mode can be confirmed to be a single-layer storage unit mode; if the storage mode type is a multi-layer storage mode, the default storage mode can be confirmed to be a double-layer storage unit mode, a three-layer storage unit mode or a four-layer storage unit mode.
As can be seen from the above, in this embodiment, by reading a target field in a local otp register, then determining a storage mode type corresponding to the target field, and finally determining a default storage mode based on the storage mode type, and performing data storage in the default storage mode. Therefore, the default working mode of the flash memory can be flexibly changed by setting the target field in the one-time programmable register, so that different SSD main control manufacturers are compatible, the limitation of the mode entering mode of the flash memory is avoided, and the compatibility of the flash memory is improved.
The embodiment of the application discloses a specific data storage method applied to a flash memory, and referring to fig. 2, the method may include the following steps:
step S21: receiving a mode entering instruction sent by a main control chip; and carrying out a power-on initialization flow based on the mode entering instruction.
In this embodiment, after the flash memory is reset, a mode entry instruction, for example, a set feature instruction, an A2 command, a DA command, etc., sent by the main control chip, i.e., the SSD main control is received; after receiving the mode entering instruction, the power-on initialization process is started to be executed.
Step S22: the target field in the local otp register is read.
In this embodiment, after entering the power-on initialization process, the flash memory actively reads the target field in the local otp register. In this embodiment, the creating process of the target field may include: one bit is added in the one-time programmable register as the target field for identifying the storage mode type. It will be appreciated that the target field is created by adding 1bit of characters in advance in a one-time programmable register, i.e. an OTP register. It is also possible to add a plurality of bit characters in the OTP register in advance to create the above-mentioned target field.
Step S23: if the target field is a first preset identifier, determining that the storage mode type corresponding to the target field is a single-layer storage unit mode; and if the target field is a second preset identifier, determining that the storage mode type corresponding to the target field is a multi-layer storage unit mode.
In this embodiment, after the target field is read, whether the character of the target field is a first preset identifier or a second preset identifier is determined, and if the target field is the first preset identifier, the storage mode type corresponding to the target field is determined to be a single-layer storage unit mode; if the target field is the second preset identifier, determining that the storage mode type corresponding to the target field is a multi-layer storage unit mode. It can be understood that the target field may be "1" or "0", or may be different character segments composed of 1/0, that is, two different target fields are preset, so that two storage unit modes can be respectively represented. For example, when the target field is "1" or "0", and the first preset identifier is "1" and the second preset identifier is "0", and when the target field is identified as the first preset identifier, determining that the storage mode type corresponding to the target field is a single-layer storage unit mode; and if the target field is distinguished to be the second preset identifier, determining that the storage mode type corresponding to the target field is a multi-layer storage unit mode.
In this embodiment, after adding a bit in the otp register as the target field, the method may further include: establishing an association relation between the first preset identifier and the single-layer storage unit mode; and establishing an association relation between the second preset identifier and the multi-layer storage unit mode. It can be appreciated that the character "1" can be used as a first preset identifier and an association can be created with the single-layer memory cell pattern before adding the target field to the otp register; also, the character "0" is used as a second preset identifier, and an association relationship is created with the multi-layered memory cell pattern. So that the flash memory determines the corresponding storage mode type after reading the target field.
Step S24: if the preset storage mode type is a single-layer storage unit mode, determining that the default storage mode is the single-layer storage unit mode; if the preset storage mode type is a multi-layer storage unit mode, determining that the default storage mode is any one of a double-layer storage unit mode, a three-layer storage unit mode and a four-layer storage unit mode.
From the above, after receiving the mode entry instruction sent by the main control chip, the flash memory actively reads the target field in the local one-time programmable register, determines the default storage mode according to the target field, and stores data based on the determined default storage mode. Therefore, compared with the prior art, the method and the device depend on a master control manufacturer to promote the compatibility of boot codes and know the follow-up programming of the memory manufacturer to improve the compatibility of the flash memory, the method and the device have the advantages that the default storage mode of the flash memory is specified by adding one bit in the OTP register, after the master control performs power-on reset operation on the flash memory, the flash memory actively reads and enters the default storage mode, the master control does not need to switch modes in the boot codes any more, program codes related to firmware of a product are directly read, and the compatibility of the flash memory is improved. The invention is easy to realize, occupies less resources, and only needs 1bit OTP resources.

a storage mode type determining module 12, configured to determine a storage mode type corresponding to the target field;

Therefore, the default working mode of the flash memory can be flexibly changed by setting the target field in the one-time programmable register, so that different SSD main control manufacturers are compatible, the limitation of the mode entering mode of the flash memory is avoided, and the compatibility of the flash memory is improved.
In some specific embodiments, the storage mode type determining module 12 may specifically include:
