Abstract

A mapping table HF update technique for a FLASH memory is disclosed. In the disclosed data storage device, when a master buffer block selected from a plurality of blocks of a FLASH memory to buffer write data from a host is full, the controller updates a logical-to-physical address mapping table for the master buffer block in separated update sub-intervals. Between the separated update sub-intervals, the controller responds to commands from the host. In this manner, commands from the host are responded to in a timely manner, without being postponed by a time-consuming mapping-table update of an entire buffer block.
