A booster for generating stable boosted voltage with respect to fluctuation of power supply voltage and load current. The booster has a charge pump circuit including a plurality of boosting units connected in series to selectively validate the boosting units and generate the boosted voltage in accordance with the number of validated boosting units. A boost control circuit is connected to the charge pump circuit to determine whether the boosted voltage is in a predetermined range and change the number of validated boosting units in accordance with the determination. |
