Abstract
A boosting unit comprises a plurality of boosting circuits. Each boosting circuit includes an input driving circuit, a switching circuit, a capacitor circuit, and a precharge circuit. The input driving circuit drives a corresponding external boosting signal. The switching circuit transfers either a power supply voltage, a ground voltage, or a boosting signal from one of the other boosting circuits to the capacitor circuit under the control of the corresponding external boosting signal. The capacitor circuit boosts up a boosting node, which has been precharged to a power supply voltage level by the precharge circuit, to predetermined voltage level higher than an input voltage level. The boosting circuits are connected together in series and simultaneously carry out a boosting operation. The boosting unit therefore provides a desired boosted voltage level at high speed.
