Abstract: A high-performance data storage device is disclosed. A non-volatile memory stores a logical-to-physical address mapping table that maps logical addresses recognized by a host to a physical space in the non-volatile memory. The logical-to-physical address mapping table is divided into a plurality of sub mapping tables. A memory controller utilizes temporary storage when controlling the non-volatile memory. The memory controller plans a sub mapping table area in the temporary storage to store sub mapping tables corresponding to a plurality of nodes which are linked and managed by multiple linked lists.
