Abstract
A semiconductor integrated circuit that includes a circuit block having a predetermined function, a power switch capable of supplying an operating power to the circuit block, and a current measuring circuit for obtaining a current flowing to the circuit block based on a voltage between terminals of the power switch in a state in which the power switch is turned on and an on-resistance of the power switch. Thus, it is possible to measure a current of the circuit block in a state in which a chip is normally operated.
