Abstract

A data storage device is provided. The data storage device includes a flash memory, a dynamic random access memory (DRAM), and a memory controller. The flash memory is configured to store a logical-to-physical mapping (L2P) table that is divided into a plurality of group-mapping (G2P) tables. The memory controller includes a first processing core and a second processing core. The first processing core receives a host access command from a host. When a specific G2P table corresponding to a specific logical address in the host access command is not stored in the DRAM, the first processing core determines whether the second processing core has loaded the specific G2P table from the flash memory to the DRAM according to the values in a first column in a first bit map and in a second column of a second bit map.
