Method for enhancing data protection performance, and associated personal computer and storage medium

Abstract

A method for enhancing data protection performance is provided. The method is applied to a personal computer that includes / is electronically connected to a memory device, and the memory device includes a Flash memory. The method includes: with regard to data to be written / programmed into the Flash memory of the memory device by the personal computer, generating at least one Error Correction Code (ECC) corresponding to the data, and storing the ECC into a file within the personal computer, wherein the file is stored in a storage of the personal computer; and when it is detected that an uncorrectable error of at least one portion of the data stored in the Flash memory occurs, performing error correction according to the ECC stored in the file, in order to correct the data stored in the Flash memory. An associated personal computer and a storage medium storing an associated driver are further provided. The present invention can greatly enhance data protection performance. In addition, in a situation where the chip area of the memory device mentioned above and the associated costs are not increased, the present invention can achieve the goal of enhancing data protection performance with regard to data in the memory device.

Description

technical field [0001] The present invention relates to access of flash memory (Flash Memory), especially a method for improving data protection performance, a related personal computer (Personal Computer), and a storage medium storing a related driver program. Background technique [0002] In recent years, due to the continuous development of flash memory technology, various portable memories (for example: memory cards conforming to SD / MMC, CF, MS, XD standards) or solid state drives (Solid State Drive, SSD) with flash memory are widely implemented in in many applications. Therefore, access control of flash memory in these memories has become a very hot topic. [0003] As far as the commonly used NAND flash memory is concerned, it can be mainly divided into two types of flash memory: single level cell (Single Level Cell, SLC) and multiple level cell (Multiple Level Cell, MLC) flash memory. Each transistor in the single-level cell flash memory, which is used as a memory ce...

AI Technical Summary

Problems solved by technology

For example, the management mechanism of related technologies cannot arbitrarily increase the number of basic error correction bits of the Error Correction Code Engine (ECC Engine)

In addition, once the basic error correction bit number of the error correction code engine is increased, the cost of the error correction code engine will increase significantly; for example, the basic error correction bit number is changed from 24 Increasing the number of bits to 36 bits will cause a large increase in the chip area of ​​the error correction code engine, which is about 1.5 times larger
