Abstract:
A data merging method for merging data belonging to a first logical block in a rewritable non-volatile memory module is provided. The method includes getting a second physical block from a free area of the rewritable non-volatile memory module and determining whether a valid logical page number is smaller than a predetermined number. The method also includes, when the valid logical page number is smaller than the predetermined number, storing a corresponding page mapping table in a start physical page of the second physical block and writing at least one valid page data belonging to the first logical block into at least one physical page of the second physical block. Accordingly, the method can effectively shorten the time for merging data.
