A memory controller includes a security key and parameter storage unit and a security engine. The security key and parameter storage unit stores at least one security key and at least one parameter that are used during encryption or decryption. The security engine receives encrypted data stored in an external boot memory, decrypts the received encrypted data by using the security key and the parameter, and outputs the decrypted data to a central processing unit (CPU), in a security operation mode.
