A semiconductor device includes a voltage hold circuit that raises a second boosted voltage with rise of an output voltage of a booster circuit that generates a first boosted voltage and then maintains the second boosted voltage at a point when the output voltage reaches a hold voltage level after that, and a first switch that short-circuits a first output terminal through which the first boosted voltage is output and a second output terminal through which the second boosted voltage is output until the output voltage reaches the hold voltage level.
