部記憶装置。 A battery that stores data; an interface that converts signals from the computer into a level that can be handled by the memory access circuit; and a memory that manages data exchange between the computer and the IC memory and data access to the IC memory. The IC memory is connected to a computer via an access circuit, and converts AC voltage into DC voltage through a memory backup power supply circuit that supplies an operating voltage for data storage when the AC power is cut off. An external storage device for a computer, characterized in that it is connected to a DC constant voltage power supply circuit that supplies an access circuit and an interface.
