ABSTRACT:
In a semiconductor device, a main circuit is operated by a first clock signal, and at least one characteristic evaluating circuit is operated by a second clock signal whose frequency is higher than a frequency of the first clock signal. Also, at least one deterioration detecting circuit is connected to the characteristic evaluating circuit and Is adapted to detect deterioration of the characteristic evaluating circuit.
