DATA WRITING METHOD AND MEMORY CONTROLLER

원문 (중국어)

A memory controller and data writing method are provided. The data writing method includes: obtaining and storing a first instruction sequence comprising a plurality of write instructions to a buffer memory; determining a plurality of first write instructions that satisfy preset conditions according to first information and second information of the write instructions; performing ascending order arrangement on the plurality of first write instructions to form a second instruction sequence; according to the second instruction sequence, sequentially executing each first write instruction so as to write sequential write data into a rewritable non-volatile memory module. As such, the write data corresponding to sequential write instructions can be effectively written sequentially into the rewritable non-volatile memory module, so as to actually execute sequential write operation required by a host system, thereby reducing random write operations caused by multi-threading and improving overall data access capability of a storage device.
