A storage device includes a flash memory array and a controller. The flash memory array includes a plurality of blocks. A minimal erase number of blocks have a minimal erase count in the plurality of blocks. When one of the minimal erase number of blocks is erased, the controller subtracts 1 from the minimal erase number.

Storage devices and data retention methods thereof

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.
