Abstract
The power control circuit of the disclosure is configured for a logic circuit performing a predetermined logic calculation on a plurality of input signals from a memory part and outputting a plurality of output signals after logic calculation. The power control circuit includes a switch part that switches between whether to supply a power voltage to the logic circuit or not; a plurality of detector circuits that respectively detect change of signal level of the input signals, wherein when the change of signal level is detected, detect signals are output respectively; and a control circuit that controls the switch part to supply power voltage to the logic circuit based on at least one detect signal from the detector circuits, wherein on the other hand, when the detect signal is not output from the detector circuits, controls the switch part not to supply power voltage to the logic circuit.
