Abstract

A semiconductor device that includes a clock generator which generates a clock signal; a booster which boosts a supply voltage by using the clock signal to output the boosted voltage; a potential detector which detects an output potential of the booster to output a frequency changing signal depending on the output potential; and a frequency changer which is interposed between the clock generator and the booster to change the frequency of the clock signal from the clock generator to the booster on the basis of the frequency changing signal.
