Abstract:
1. A data writing method for a rewritable non-volatile memory module, wherein the rewritable non-volatile memory module comprises a plurality of physical erasing units, each of the physical erasing units comprises a plurality of physical programing units, and the physical erasing units are grouped into at least a data area, the data writing method comprising: configuring a plurality of logical addresses to map to the physical erasing units in the data area; grouping at least one physical erasing unit among the physical erasing units besides the physical erasing units in the data area into a first buffer area; and grouping at least one physical erasing unit among the physical erasing units besides the physical erasing units in the data area into a second buffer area, wherein the at least one physical erasing unit of the first buffer area is different from the at least one physical erasing unit of the second buffer area; receiving a first write command, wherein the first write command instructs to write a first data to a first logical address among the logical addresses; determining whether a quantity of the first data is smaller than a predetermined value;
