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.
