Abstract
PURPOSE:To realize the miniaturization and the low price of a power unit, by providing an interface memory which delivers an instruction and information between a central processing unit (CPU) and a disk controller (DKC), and providing a power source with a battery backup circuit capable of supplying a power only to the interface memory, the DKC, and a disk unit (DKU). CONSTITUTION:The interface memory 1-5 which delivers the information required for the control of the DKU1-8 is provided between the CPU1-1 and the DKU1-8. The DKC1-6 controls the write of data on a designated area in the DKU1-8 according to the instruction of the CPU1-1 or the readout of the data from the designated area. And the power unit 1-13 for the interface memory 1-5, the DKC1-6, and the DKU1-8 incorporates the battery backup circuit 1-14. Consequently, it is possible to hold normal output until the instruction under execution on the DKU1-8 is completed normally even when momentary power disconnection occurs in an AC input current 1-12 or power failure is generated. In such a way, it is possible to miniaturize the power unit.
