Abstract
Provided is a boosting circuit. The boosting circuit includes a voltage generator, a booster, a voltage detector, and a selector. The voltage generator receives an external first voltage to output a second voltage. The booster boosts an input voltage to output a third voltage. The voltage detector detects at least one voltage level of the first to third voltages to output a selection signal. The selector transfers one of the first and second voltages as the input voltage of the booster in response to the selection signal.
