Abstract: In transmission of command from a host device to a memory device, circuitry is configured to selectively switch between a first pattern and a second pattern. In the first pattern, an encrypted command is generated by encrypting a command with an S-box circuit of a first encryption unit, and the encrypted command is decrypted with an InvS-box circuit of a second decryption unit. In the second pattern, an encrypted command is generated by encrypting a command with an InvS-box circuit of a first decryption unit, and the encrypted command is decrypted with an S-box circuit of a second encryption unit.
