Abstract:
The communication device sends an authentication code (N) to a semiconductor memory to instruct the semiconductor memory to authenticate the communication device. The semiconductor memory authenticates the communication device based on the authentication code (N), and if the communication device is determined to be valid, sends an authentication code (N+1) to the communication device to instruct the communication device to authenticate the semiconductor memory in response to the authentication code (N). The communication device authenticates the semiconductor memory based on the authentication code (N+1).
