CONTROLLER, FLASH MEMORY APPARATUS, METHOD FOR IDENTIFYING DATA BLOCK STABILITY, AND METHOD FOR STORING DATA IN FLASH MEMORY APPARATUS

摘要

embodiment of this invention the processor, cache, and provides a controller comprising a communications interface, a flash memory device, to store with the data blocks having the same reliability level controller of claim from cache reading information on the first data block, and the period first reference count and the data block of the reference count, the first data block of a data block length of the period that is stored in the flash memory device, and the data block is stored in the flash memory device determine the stability of the level of the first data block according to the mapping relationship between the length and the level and stability-stable level is used to indicate the reliability of the data block; And it consists of the reliability level of the first data block of the logical address (logical address) of the first data block to be transmitted to the flash memory device via the communication interface. ;
