Abstract
A data writing method for controlling a rewritable non-volatile memory module having physical erasing units is provided. The physical erasing units are grouped into a first buffer area and a second buffer area. A write command instructed to write a data to a first logical address is received. Whether the quantity of the data is smaller than a predetermined value is determined. If so, the data is written into the first buffer area or the second buffer area. If the data is written into the second buffer area, at least one second logical address mapped to at least one physical programing unit in the first buffer area is obtained, and valid data belonging to the second logical address is merged, wherein the number of the second logical address is smaller than a merging threshold. Thereby, the time for a host system to wait for a write success message is shortened.
