Abstract

The invention is suitable for the technical field of flash memories, and particularly relates to a flash memory data analysis method and device, terminal equipment and a storage medium. According to the method, data writing is executed for each flash memory block in the flash memory, the writing temperature during data writing is recorded, and in a test temperature range, the data in each flash memory block is read, and the reading temperature during data reading is recorded; and the identification information of the flash memory block with the read error and the bit number, the read temperature and the write-in temperature of the read error corresponding to the flash memory block are obtained, the information of the flash memory block with the read error is used for generating an analysis table, and the read-write performance test of the flash memory is realized. According to the bit number of the read error of the flash memory block under the temperature condition, the test result of each flash memory block can be more accurately obtained in combination with the temperature condition so as to judge the reliability of the flash memory.

Description

technical field [0001] The present application belongs to the technical field of flash memory, and in particular relates to an analysis method, device, terminal equipment and storage medium of flash memory data. Background technique [0002] Flash memory is flash memory, which has the advantages of fast access speed, high performance, and low power consumption, and is widely used in storage solutions. As the storage capacity of flash memory increases, the number of bits of storage units in flash memory also increases, which makes the built-in error correction function of flash memory unable to meet the requirements of ensuring the reliability of flash memory. Therefore, in order to ensure the reliability of flash memory, read and write to flash memory Performance testing is particularly important. Contents of the invention [0003] In view of this, the embodiments of the present application provide a flash memory data analysis method, device, terminal equipment, and stora...
