Abstract
A booster apparatus includes a voltage conversion control circuit configured to generate second power supply voltage, based on the ground voltage, first power supply voltage, and a driving clock signal. The voltage conversion control circuit includes: a booster circuit configured to generate the second power supply voltage based on an input booster clock signal; a clock buffer configured to generate the booster clock signal and output the generated booster clock signal to the booster circuit; and a voltage comparator that includes: a first voltage generation circuit configured to generate a first signal with a first voltage level; a second voltage generation circuit configured to generate a second signal with a second voltage level; and a comparator configured to compare the first voltage level and the second voltage level and control input of the driving clock signal to be supplied to the clock buffer based on a comparison result.
