Abstract: A memory management method applicable to a data storage device is provided. The memory management method includes steps of: requesting a private memory space from a host; recording a reserved memory space given by the host; dividing a mapping table into a plurality of sub-mapping tables; determining whether a capacity of the reserved memory space is sufficient to store the sub-mapping tables; and if yes, uploading the sub-mapping tables to the reserved memory space via an interface logic.
