Abstract
A semiconductor device, including a circuit configuration formed on a semiconductor substrate, comprises: a boosting circuit for boosting an external power supply voltage to a plus voltage and a minus voltage; and a detecting circuit having a resistor formed of an impurity diffused layer so that the plus voltage and the minus voltage boosted by the boosting circuit are respectively connected to the resistor, to detect a potential at a prescribed point of said resistor so as to verify whether or not the boosting circuit has generated a desired potential.
