Problems solved by technology

[0002] NOR FLASH is a non-volatile flash memory technology. NOR FLASH memory has always been recognized as a relatively stable storage medium. However, recent studies have found that NOR FLASH also has the problem of bit flipping, which is related to the manufacturing process and documentation of chip suppliers. It is related to the number of access times, and the current NOR FLASH controller chips rarely support ECC verification, so the reliability of storing and reading files in NOR FLASH is low

Abstract

The invention discloses a method for storing and reading files in NOR FLASH, which includes: when a file needs to be stored in NOR FLASH, the length information of the file to be stored is encoded according to a preset first BCH cyclic code, and according to the preset The set second BCH cycle code encodes the content information of the file to be stored; stores the file to be stored according to the encoded file; when the file needs to be read in NOR FLASH, according to the preset third BCH cycle The code decodes the length information of the file to be read, and decodes the content information of the file to be read according to the preset fourth BCH cycle code; obtains the file to be read according to the decoded file. Correspondingly, the invention also discloses a device for storing and reading files in NOR FLASH and a computer-readable storage medium. The technical scheme of the invention can solve the bit flip problem of NOR FLASH, thereby improving the reliability of storing and reading files in NOR FLASH.

Description

technical field [0001] The invention relates to the technical field of data access, in particular to a method, device and computer-readable storage medium for storing and reading files in NOR FLASH. Background technique [0002] NOR FLASH is a non-volatile flash memory technology. NOR FLASH memory has always been recognized as a relatively stable storage medium. However, recent research has found that NOR FLASH also has the problem of bit flipping, which is related to the manufacturing process and documentation of chip suppliers. It is related to the number of access times, and the current NOR FLASH controller chips rarely support ECC verification, so the reliability of storing and reading files in NOR FLASH is low. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a method, device and computer-readable storage medium for storing and reading files in NOR FLASH, which can solve the bit flip proble...
