Abstract

See full text

A data storage apparatus includes storage including a plurality of memory blocks and a controller configured to set an attribute of each of the memory blocks as a random memory block or a sequential memory block, and to manage validity of map data for data stored in each of the memory blocks using a map segment bitmap. The controller configures at least one memory block set by combining a set number of memory blocks, as a housekeeping event is triggered, and selects a victim block set from the at least one memory block set based on continuity of a logical address, or a number of valid map data, or both.
