A high voltage generator generates a high voltage higher than a power-supply voltage by a predetermined potential in order to supplement a loss of a threshold potential of a transistor in a semiconductor memory device. The high voltage generator has each potential sensing unit for a standby mode and active mode. In case of the standby mode, the high voltage generator minimizes a current consumption, and stably generates a high voltage. In case of the active mode, the high voltage generator limits a potential variation width of high voltage, thereby stably generating a high voltage at a high-speed.
