Abstract
In the semiconductor circuit device of the present invention, the switching circuit 10 connects the power supply pin 4 to the capacitance 9 before the input signal 2 to the semiconductor circuit 1 is changed so that the electric charge of the semiconductor 1 is stored in the capacitance 9, and when the input signal 2 is changed, the semiconductor circuit 1 is charged with the electric charge stored in the capacitance 9. And, after the input signal 2 is changed, the switching circuit 10 connects the power supply pin 4 to a power supply to charge the semiconductor circuit 1.
