Abstract
A semiconductor integrated device has a detection cell arranged in a power-supply line in the semiconductor integrated device and detecting a power-supply voltage. Further, a detection circuit detects a voltage drop of the power-supply voltage detected by the detection cell. Connection wiring connects the detection cell and the detection circuit and outputs the power-supply voltage detected by the detection cell to the detection circuit.
