摘要

PROBLEM TO BE SOLVED: To stably transfer data at a high speed while keeping a present specification in a device such as a cellular phone terminal provided with an interface of a semiconductor memory.

SOLUTION: A connector to be inserted to a slot for miniSD of the cellular phone terminal 6 is prepared on a data management device main body 2. Further, the data management device main body 2 comprises a virtual memory management part 21 for virtualizing the storage area of the miniSD in a hard disk whose capacity is larger than the miniSD, a data write processing part 22 for writing the data transmitted from the cellular phone terminal 6 through the connector to a virtual memory VMR which is the virtualized storage area, and a data read processing part 23 for transmitting the data stored in the virtual memory VMR through the connector to the cellular phone terminal 6.
