Abstract: PROBLEM TO BE SOLVED: To more improve the trimming accuracy of the internal reference voltage of a semiconductor integrated circuit device. SOLUTION: A voltage comparison discriminating circuit 20 discriminates the necessity/nonnecessity of the trimming of an internal reference voltage VREF generated by means of an internal reference power source circuit 10, by comparing the voltage VREF with a set voltage VE impressed upon a bonding pad 16 from the outside.
