Title: Semiconductor integrated circuit device
Inventor: SONOYAMA HIROSHI
IPC: G11C16/06
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To greatly improve the reliability of a semiconductor integrated circuit device by reducing the dispersion of detection levels in power source voltage caused by temperature, a manufacturing process and the like. SOLUTION: The voltage difference between reference voltage VREF generated by a reference voltage generating section 16 and detection voltage to which power source voltage VCC is voltage-divided by resistors 27, 28 is amplified differentially by a differential amplifying circuit SA and outputted as a detection signal K. Since the reference voltage generating section 16 generates reference voltage VREF from the voltage between a base and an emitter in a bipolar type transistor in which dispersion caused by temperature and a manufacturing process is small, dispersion of a detection level in power source voltage VCC can be made small.
