Abstract
A voltage generator includes a boosting circuit boosting a power voltage to generate first through fourth voltages, and a boosting controller controlling the boosting circuit. The boosting controller sets the third and fourth voltages to a voltage level lower than that of a ground voltage while the first and second voltages are generated, so that a plurality of voltages may be stably generated, i.e., without latch-up.
