摘要
A data storing method for storing data in a rewritable non-volatile memory module is provided. The method includes temporarily storing first data into a buffer memory; and starting a flush operation to write the first data from the buffer memory into a first physical programming unit. The method further includes determining whether the first physical programming unit is a lower physical programming unit; and if yes, writing second data into a second physical programming unit, wherein the second physical programming unit belongs to an upper physical programming unit, and the second physical programming unit and the first physical programming unit are formed by the same memory cells disposed on the same word line. Accordingly, the method can effectively prevent the data written during the flush operation from losing due to the programming fail occurred on other physical programming units.
