Abstract
A controller is coupled to a non-volatile memory device and a host. The controller is configured to perform a cyclic redundancy check on map data associated with user data stored in the memory device, generate an encryption code based on a logical address included in the map data, generate encrypted data through a logical operation on the encryption code and the map data, and transmit the encrypted data to the host.
