PURPOSE: A power up circuit of a semiconductor device is provided to prevent the malfunction of a circuit by including a discharge unit. CONSTITUTION: A reference voltage generating unit(110) divides power voltage. The reference voltage generating unit generates a reference voltage. A power up signal generating unit(120) uses the power voltage and the reference voltage. The power up signal generating unit generates the power up signal. A discharge unit(130) discharges the reference voltage.
