Abstract

A data storage device and a flash memory control method with high efficiency are disclosed. The random access memory of the data storage device is allocated to provide a collection and update area for logical-to-physical address mapping tables that correspond to logical addresses recorded into the physical-to-logical address mapping table. When recording a logical address corresponding to a new logical-to-physical address mapping table that has not appeared in the collection and update area into the physical-to-logical address mapping table, the microcontroller of the data storage device is configured to collect the new logical-to-physical address mapping table into the collection and update area and perform an update of the new logical-to-physical address mapping table within the collection and update area.
