Abstract
In a semiconductor device, an abnormality monitor unit detects whether abnormal leakage current has been generated from a first functional module or a second functional module on the basis of a comparison between a change in voltage at a first node between the first functional module and a first power switch when the first power switch is in an off state and a change in voltage at a second node between the second functional module and a second power switch when the second power switch is in the off state.
