Abstract: A data merge method for a rewritable non-volatile memory module including a plurality of physical units is provided. The method includes: selecting at least one first physical unit and at least one second physical unit from the physical units; reading first mapping information from the rewritable non-volatile memory module, and the first mapping information includes mapping information of the first physical unit and mapping information of the second physical unit; copying valid data collected from the first physical unit and valid data collected from the second physical unit to at least one third physical unit of the physical units according to the first mapping information; and when a data volume of valid data copied from the second physical unit to the third physical unit reaches a data volume threshold, stopping collecting valid data from the second physical unit, and continuing collecting valid data from the first physical unit.
