摘要：
A semiconductor integrated circuit device includes a reference voltage generating circuit outputting a reference voltage from a step-up voltage, a step-up circuit stepping up the reference voltage within a range lower than an external power supply voltage and thus outputting the above step-up voltage, a step-down circuit stepping down the external power supply voltage and thus outputting a step-down voltage equal to the reference voltage, and an internal circuit receiving, as a power supply voltage thereof, the step-down voltage.
