<p>A voltage generation circuit has N sets of voltage step-up circuits configured to start a voltage step-up operation for increasing an absolute value of an output voltage and configured to stop the voltage step-up operation when the output voltage reaches a step-up voltage that is independently set for each voltage step-up circuit; and a control circuit configured to control such that the N sets of voltage step-up circuits operate in accordance with order of priority while limiting a maximum number of voltage step-up circuits that simultaneously operate, out of the N sets of voltage step-up circuits, to a plural number lower than the N sets.</p> |
