Abstract
A data storage device includes a memory device and a memory controller. When a sub-region of the memory device is selected based on a predetermined rule to perform a data rearrangement procedure, the memory controller determines whether the selected sub-region is a system data sub-region. When determining that the selected sub-region is not a system data sub-region, the memory controller performs the data rearrangement procedure on the selected sub-region to move data corresponding to logical addresses belonging to the selected sub-region to a memory space of the memory device having continuous physical addresses, and when determining that the selected sub-region is a system data sub-region, the memory controller does not perform the data rearrangement procedure on the selected sub-region.
