Patent abstract
A pumping voltage detector includes a first division voltage generating unit for dividing a pumping voltage at a first division ratio to generate a first divided voltage, a second division voltage generating unit for dividing the pumping voltage at a second division ratio different from the first division ratio to generate a second divided voltage, and a detection signal generating unit for comparing one of the first and second divided voltages with a reference voltage to generate a pumping voltage detection signal.
