ABSTRACT:
The memory card with a simple configuration is provided with more reliable security. When the memory card receives the access request to the memory from the external connecting device, the access unit accesses the memory based on the access request. At this time, the switch composing the memory card indicates the propriety of the access right to the memory, and the access limitation unit limits that the access unit accesses the memory.
