Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0039] Such as figure 1 As shown, the FTL with data compression function is mainly composed of a compressor Compressor, a decompressor Decompressor, a buffer buffer, an address mapping management module, a garbage collection module and a loss leveling module. Compressor compresses the data to be written sent by the host and writes it into Buffer; Decompressor decompresses the data read from Buffer or flash memory and returns it to the host; Buffer receives the compressed data sent by Compressor and splices it into several complete flash data pages ; The address mapping management module is responsible for the correctness of the address mapping relationship in the entire reading and writing process; the garbage collection module is responsible for reclaiming the invalid flash memory blocks; the loss leveling module is responsible for balancing the erasing and ...
