Abstract
The present invention proposes a method for managing a plurality of memory units in a flash memory module. The method includes: creating a programed timestamp corresponding to each first memory unit according to a data-written time of said each first memory unit; selecting a corresponding read-retry table for performing a read operation upon said each first memory unit according to the programed timestamp of said each first memory unit; and performing a first refresh operation according to program timestamps of first memory units that have been written with data.
