Abstract: In some embodiments, the memory system for communicating with a host includes a non-volatile memory device storing first mapping information, a volatile memory device storing second mapping information, and a memory controller. The first mapping information indicates a relationship between a logical address and a portion of a first physical address. The first physical address indicates a location where user data is stored. The second mapping information indicates a second relationship between the logical address and a second physical address that corresponds to a remaining portion of the first physical address. The memory controller is configured to obtain a target logical address that has been received from the host, and determine, based on the second mapping information, a target second physical address mapped to the target logical address. The non-volatile memory device is configured to obtain a target first physical address by using the first mapping information.
