ABSTRACT:
A semiconductor integrated circuit device includes a comparator for making a comparison between a logical value of an input signal and a logical value of an output signal and outputting a combination signal having a combination of the logical values; and a flip-flop circuit configured to maintain a state of the output signal with electric power for maintaining the state less than electric power for state transition of the output signal in the case where the combination of the logical values of the combination signal is a predetermined combination, and wherein the comparator outputs the combination signal having the predetermined combination to an input terminal portion in the case of determining that the input signal does not vary the state of the output signal based on a result of the comparison between the logical value of the input signal and the logical value of the output signal.
