Abstract:
1. A semiconductor device, comprising: a first circuit supplied with a first power source potential and a second power source potential which is lower than the first power source potential; a second operating circuit supplied with the first power source potential and the second power source potential; a first terminal for receiving the first power source potential from the outside; a second terminal for receiving the second power source potential given from the outside; a first power source supply line for electrically coupling the first terminal with the first circuit; a second power source supply line for electrically coupling the second terminal with the first circuit; a third power source supply line for electrically coupling the first terminal with the second circuit; a fourth power source supply line for electrically coupling the second terminal with the second circuit; a capacitive element coupled between the first power source supply line and the second power source supply line; a first field-effect transistor of conductive type which is inserted in and coupled to the first power source supply line and whose gate is coupled to the second source power supply line; and a second conductive-type field-effect transistor which is inserted in and couple to the second power source supply line and whose gate is coupled to the first power source supply line.
