Abstract: An operating method of a memory controller may include: enabling a security mode in response to a first command received from a host; generating a security key based on a host key received from the host; storing the security key in a security key storing unit; and/or performing a first data processing operation of encrypting data received from the host and decrypting data stored in a non-volatile memory device, based on the security key, when the security mode is enabled. The security key storing unit may be a volatile memory.
