APPARATUS AND METHOD FOR INCREASING OPERATION EFFICIENCY IN A MEMORY SYSTEM

摘要

A data processing system of the present invention includes: a memory system including a memory device including a plurality of memory blocks; and a host that divides the memory device into a plurality of logical blocks and includes a plurality of segments formed of at least some of the plurality of logical blocks, wherein the host is selected based on the number of valid logical blocks corresponding to the memory blocks. A segment is selected, segment recycling is performed on the victim segment, and at least one memory block is invalidated by the segment recycling.
