A semiconductor integrated circuit device is equipped with a step-down circuit for producing a step-down power voltage from a power voltage level, and first and second component circuits of the semiconductor integrated circuit device are coupled between the power voltage line and the step-down power voltage line and between the step-down power voltage line and the ground voltage line, respectively, so that current passing through the first component circuit is reused by the second component circuit, thereby improving current consumption.
