Abstract

The invention relates to a method and a system for the data writing of flash memory storage equipment. The method comprises the following steps: receiving a data writing operation command sent for the flash memory storage equipment, wherein the data writing operation command comprises data to be written and a logical address of the data to be written; storing the data to be written in one or more data buffer areas according to the data writing operation command; writing the data in the buffer areas into a storage unit, which is directed by the logical address, of the flash memory storage equipment; carrying out ECC (Error Correcting Code) check on the data which are written through the data buffer areas; rewriting the data of the data buffer areas when the number of error bytes checked exceeds an ECC threshold, and carrying out ECC check on the rewritten data until the number of the error bytes checked does not exceed the ECC threshold. Through repeatedly checking the data written in the storage unit until the data written in the storage unit are correct, the accuracy of data access is guaranteed, and the stability and reliability of data writing are improved.

Description

technical field [0001] The invention relates to a storage device, in particular to a method and system for writing data in a flash memory storage device. Background technique [0002] When traditional flash storage devices are used for data storage and reading, they undergo repeated erasing and writing operations, that is, the process of charging and discharging, their lifespan will be shortened, and their performance will decrease, which may cause Data access errors are prone to occur when the flash memory storage device is continued to be used subsequently. Contents of the invention [0003] Based on this, it is necessary to provide a method for writing data in a flash storage device that can ensure accurate data access in view of the problem that traditional flash storage devices are prone to data access errors due to repeated erasing and writing operations. [0004] In addition, it is also necessary to provide a data writing system for flash storage devices that can e...
