<P>PROBLEM TO BE SOLVED: To provide a control device and a storage device which do not require a long charge time and battery replacement, and which, when the power supply is cut off, can normally terminate access to a nonvolatile storage unit by a power storage unit having small power storage capacity. <P>SOLUTION: A control device and a storage device 1 comprise a first power supply unit 101, a first power storage unit 102, a second power supply unit 105, a second power storage unit 106 including a capacitor, a first switch, a central control unit 109 which accesses a nonvolatile storage unit 107 through the first switch, a third power supply unit 110, a voltage detection unit 103 which outputs the measured value of a first voltage, and a power source control unit 104 which controls the central control unit 109, the first switch 108, and the third power supply unit 110 on the basis of the measured value of the first voltage. Depending on a drop in the measured value of the first voltage, the power source control unit 104 causes access by the central control unit 109 to stop and turns the first switch 108 off, thereby causing power supply by the third power supply unit 110 to stop. <P>COPYRIGHT: (C)2013,JPO&INPIT |
