Abstract
A step-up circuit is equipped with a step-up clock signal generation device that generates a clock signal to be used for stepping up voltage, a plurality of step-up stages for successively stepping up a power supply voltage based on the clock signal, and control devices that controls, after starting an operation, the stepped up clock signal generated by the step-up clock signal generation device to be supplied to the plurality of step-up stages at different timings.
