Abstract: A data programming method includes setting a plurality of first type physical erasing units as a current writing area and recording a current writing data amount. The method also includes calculating a data amount threshold according to the first type physical erasing units. The method still includes receiving data. The method further includes: if the current writing data amount is less than the data amount threshold, programming the data to at least one of the first type physical erasing units using a first programming mode; and if the current writing data amount is not less than the data amount threshold, setting a plurality of second type physical erasing units as the current writing area and programming the data to at least one physical erasing unit of the second type physical erasing units using a second programming mode.
