Data updating method and device of flash memory equipment and flash memory management system

Abstract

The invention relates to a data updating method and device for flash memory devices and a flash memory management system.The method comprises the steps that a plurality of flash memory devices are mapped into corresponding file systems, each file system comprises an index file and at least one data file, the index file comprises a data type identifier, and the at least one data file comprises at least one data type identifier; each data file maps flash memory data corresponding to the data type identifier in the flash memory equipment; based on the dynamic distribution mode, establishing a first mounting connection with at least one target file system, reading contents of an index file and a data file corresponding to the to-be-updated data into a cache, and releasing the corresponding first mounting connection; updating the content of the data file read into the cache to obtain updated data; and based on the dynamic allocation mode, establishing the second mounting connection with the target file system, writing the update data into the corresponding target file system, updating the index file and writing the index file into the target file system, and releasing the second mounting connection, so that the problems that the FLASH storage management difficulty is increased and the storage management cost is relatively high are solved.
