Abstract
A memory data management method includes the following steps reading a plurality of data of a plurality of memory cells of a memory block; determining whether error bits of the data exceed an error correction code (ECC) threshold; if the error bits of the data exceed the ECC threshold, a programming process being executed to increase a first threshold voltage of a first state data of the data for exceeding a first threshold, to increase a second threshold voltage of a second state data of the data for exceeding a second threshold, and to increase a third threshold voltage of a third state data of the data for exceeding a third threshold.
