Abstract:
A memory system capable of efficiently managing meta data is provided. The memory system includes a non-volatile memory device for storing a plurality of map segment groups each including map segments including mapping information between at least one physical addresses and at least one logical address of a host; and a controller for loading one map segment from each of selected map segment groups among the plurality of map segment groups, and differently configuring flush data to be flushed to the non-volatile memory device in response to a program request that includes a first target logical address received from the host according to whether a target map segment corresponding to the first target logical address is in the loaded one map segment.
