The Disclosed is a boosting circuit. A boosting voltage (VBOOT) is rapidly increased to a given voltage level in two steps by using a preboosting circuit unit and a bootstrap circuit unit. The boosting voltage (VBOOT) is dropped through a clamp circuit unit to generate a final target voltage. Therefore, it is possible to make fast read access time in a read operation, minimize consumption of current and generate a stabilized word line voltage (W/L).
