Abstract:
A storage device includes a flash memory array and a controller. The flash memory array includes a plurality of blocks. The first block among the blocks has a minimal erase count in the blocks. When determining that a difference between an average erase count of the blocks and the minimal erase count exceeds a cold-data threshold, the controller selects the first block to be a source block. When a data migration of a data-moving process is executed, the controller moves the data of the source block to a target block.

Claim (Index 16):
The data retention method of  claim 14 , wherein a third block among the blocks has a maximum writing serial number and the third block is the latest one that has been filled among the blocks, wherein after the step of selecting the fourth block of the flash memory array to be the source block, the data retention method further comprises:\n determining whether a difference between the maximum writing serial number and the minimum writing serial number exceeds a second threshold; and if the difference between the maximum writing serial number and the minimum writing serial number does not exceed the second threshold, not executing the data migration of the wear-leveling process.
