Abstract
Off-leak electric current is reduced in the operation mode where a circuit is actually operating. In the state in which the power supply voltage is constantly applied to the front stage flip-flopstoand rear stage flip-flopstofor example, data held in the flip-flopstoat rising of the clock signal CK is processed in a logic gate circuit networkto which the supply voltage is applied during a low level period of the clock signal CK, and then, the processed data is held in the flip-flopstoIn the case where the power supply time to the logic gate circuit networkis set to minimum, off-leak electric current of the logic gate circuit networkcan be reduced.
