    Abstract: The present invention provides a memory system in which a semiconductor memory device can be accessed properly. The memory system includes a memory controller and a semiconductor memory device. The memory controller sends a command, an address, and first checking data to the semiconductor memory device. When the semiconductor memory device receives first response information that indicates that no error has been detected, it sends or receives read data or write data from the semiconductor memory device. When the semiconductor memory device receives the command, the address, and the first checking data, it uses the first checking data to detect errors in the command and the address, and sends the first reply information when no error is detected, and when no error is detected in the command and the address, it sends or receives read data or write data from the semiconductor memory device.
