Abstract
A power control device includes non-volatile memory, a controller, and a logic circuit. The non-volatile memory includes a function of externally outputting a logical state of a bit stored in a specific area as a state hold signal that indicates an ON/OFF state of a device function unit before a power cutoff. The controller controls the ON/OFF state of the device function unit and also writes the ON/OFF state of the device function unit to the specific area of the non-volatile memory. The logic circuit controls power supply to the controller on the basis of a logic level of the state hold signal from the non-volatile memory.
