Abstract
A data storage device may include a non-volatile memory device storing an address mapping table including a plurality of map segments and a controller including a random-access memory. The controller loads a compressed or non-compressed first map segment into the random-access memory based on meta-information of the first map segment in response to a read request received from a host device. The meta-information is stored in a map segment meta-information table stored in the random-access memory and the meta-information represents whether the map segments are compressible or not.
