摘要：A booster circuit includes a pump circuit that boosts a voltage supplied from apower supply and outputs the boosted voltage, and a pump controlling circuit thatoutputs a first clock signal for operating the pump circuit to control the operation of thepump circuit. The pump controlling circuit controls the pump circuit to reduce a number
of active charge pump circuits according to an output signal of one of a first comparatorand a second comparator, controls the pump circuit to reduce a frequency of a secondclock signal for operating the active charge pump circuits by reducing a frequency of thefirst clock signal according to the other output signal of one of the first comparator andthe second comparator, and brings the pump circuit into an inactive state according to anoutput signal of a third comparator.
