Patent ID: 7668568

Claim:
A data input and output device for inputting data from a semiconductor memory associating device or outputting data thereto, the semiconductor memory associating device including a mounting portion that mounts a predetermined standard semiconductor memory and including a function of writing data to the semiconductor memory or of reading data from the semiconductor memory, the data input and output device comprising: a data input and output device body; and a connector that is to be mounted to the mounting portion of the semiconductor memory associating device, the data input and output device body including a semiconductor memory simulation portion that simulates a storage area of the semiconductor memory in a storage medium having a capacity larger than that of the semiconductor memory, a data write portion that writes data in a virtual storage area that is the storage area of the semiconductor memory simulated by the semiconductor memory simulation portion, the data being sent from the semiconductor memory associating device via the connector, and a data transmission portion that sends data stored in the virtual storage area to the semiconductor memory associating device via the connector.
