Method for optimizing flash memory medium and non-volatile storage device

Abstract

The invention relates to the field of data storage, and discloses a method for optimizing a flash memory medium and a nonvolatile storage device. Wherein, the flash memory medium includes several physical blocks, and the method for optimizing the flash memory medium includes: selecting a physical block of a first proportion from the several physical blocks as a reference physical block; performing a preset number of erase / write operations on the reference physical block Operation: Acquiring reference performance parameters of reference physical blocks after performing a preset number of erase / write operations; adjusting performance parameters of remaining physical blocks according to the reference performance parameters. The embodiment of the present invention can optimize the performance of the remaining physical blocks, and improve the accuracy rate of data reading and writing of the remaining physical blocks.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a method for optimizing a flash memory medium and a nonvolatile storage device. Background technique [0002] With the development and wide application of technologies such as the Internet, cloud computing, and the Internet of Things, in human activities, it is inevitable to generate massive data that needs to be processed and stored, thus putting forward higher requirements for storage systems. Flash memory media is used as a carrier for storing data. , whose performance affects the use of storage devices or storage systems. [0003] At present, for flash media in any stage of use, when performing read and write operations, it directly reads and writes the physical blocks in the target area according to the operation instructions and the basic performance parameters of the physical blocks, but due to long-term reading and writing or non-use In a certain area, the bit inversion of th...

[0003] At present, for flash media in any stage of use, when performing read and write operations, it directly reads and writes the physical blocks in the target area according to the operation instructions and the basic performance parameters of the physical blocks. In a certain area, the bit inversion of the block area, or, with the increase of the number of erase / write operations, the medium characteristics of the flash medium change, may lead to the performance degradation of the physical block in the flash medium, resulting in data loss or read mistake
