Flash memory abnormality detection method, device, computer equipment and storage medium

Abstract

The invention discloses a flash memory abnormality detection method, device, computer equipment and storage medium, and relates to the field of information technology, and mainly lies in being able to detect the abnormality of the flash memory according to the reliability level corresponding to the flash memory, so as to avoid data loss caused by the abnormality of the flash memory Storage error. Wherein the method includes: acquiring the attribute feature corresponding to the flash memory block to be detected in the flash memory chip; inputting the attribute feature into a preset reliability prediction model for low-frequency reliability prediction, and obtaining the low-frequency prediction result corresponding to the flash memory block to be detected; if The low-frequency prediction result does not meet the requirements of the preset reliability level, then input the attribute characteristics into the preset reliability level model to perform high-frequency reliability prediction, and obtain the high-frequency prediction result corresponding to the flash memory block to be detected ; According to the high-frequency prediction result, determine whether there is abnormality in the flash memory block to be detected. The invention is suitable for abnormal detection of flash memory.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a flash memory abnormality detection method, device, computer equipment and storage medium. Background technique [0002] Solid State Disk (Solid State Disk), referred to as SSD, is a computer storage device that mainly uses flash memory as a permanent memory. Solid State Disk is composed of a control unit and a storage unit. It has fast read and write speed, strong shock resistance, low power consumption, With the advantages of no noise and light weight, it is widely used in industrial control, video monitoring, network monitoring, network terminals, navigation equipment and many other fields. The storage unit of SSD is mainly flash memory. To a certain extent, there will be errors in the data storage process, which will affect the normal use of the entire storage system. [0003] At present, the number of program-erase operations of the flash memory is usually lim...

AI Technical Summary

Problems solved by technology

However, this method greatly limits the service life of the flash memory, and it is impossible to know the actual wear of the flash memory during use, that is, it is impossible to detect the abnormality of the flash memory. Once the flash memory is abnormal, continue to store data, which will lead to data storage errors. , at the same time, this method cannot avoid the loss caused by sudden flash memory data errors
