Abstract:
A data storage device includes a flash memory and a flash memory controller. The flash memory controller operates the flash memory to store data, and stores a mapping table to record the mapping information between a plurality of logical addresses and a plurality of physical addresses of the flash memory. The mapping table is divided into a plurality of groups. Some of the groups are categorized into a first type of trim group and some of the logical addresses of each of the groups of the first type of trim group are included in a trim command. The flash memory controller performs the trim on the groups of the first type of trim group.

Claim (Index 10):
The data storage device as claimed in  claim 2 , wherein:\n when the flash memory controller receives a write command, the flash memory controller performs trimming on some of the groups if a target logical address of the read command belongs to some groups of the second-type trim groups.
