Abstract
A data writing method for a rewritable non-volatile memory module is provided. The method includes: if data belongs to a first pattern, using a first compression/decompression circuit to compress the data to generate compressed data and writing the compressed data into the rewritable non-volatile memory module; and if data belongs to a second pattern, using a second compression/decompression circuit to compress the data to generate another compressed data and writing the another compressed data into the rewritable non-volatile memory module, wherein the compression speed of the first compression/decompression circuit is higher than that of the second compression/decompression circuit, and the compression rate of the first compression/decompression circuit is lower than that of the second compression/decompression circuit.
