Method and device for dynamically predicting service life of flash memory chip online

Abstract

The invention relates to a method and a device for dynamically predicting a service life of a flash memory chip online. According to the method, reliability information of the flash memory chip is collected online, and a new life prediction operation is performed continuously, so as to overcome the defects of the conventional prediction technology, and perform the real-time predication on a remaining life of the flash memory chip.

Description

technical field [0001] The invention relates to the technical field of flash memory chip life prediction, in particular to a method and device for dynamically predicting the life of a flash memory chip online. Background technique [0002] In electronic equipment, memory has always been a very important component as a carrier for storing data. At present, memories used in electronic devices are mainly divided into two categories: volatile memories and nonvolatile memories. As a kind of non-volatile memory, flash memory chip has become the fastest-growing memory product in the fields of communication, consumption, computer, industrial control, military and other fields due to its high storage capacity and low manufacturing cost. occupies an absolutely important position in the sexual memory market. [0003] During the use of a flash memory chip, the medium of its storage unit will have defects as the number of programming / erasing cycles of the flash memory chip increases an...

AI Technical Summary

Problems solved by technology

[0004] The existing flash memory chip life prediction technology establishes a life prediction model based on the data collected once. This prediction method does not perform real-time prediction on the state of the flash memory chip, and it is difficult to predict the remaining life value in line with the actual reliability state of the flash memory.
