Internal voltage generating circuit
An internal voltage generating circuit detects a level of a back bias voltage or a pumping voltage and controls a period of an oscillating signal based on the result of counting timing when the detected voltage is lower than a reference voltage. The internal voltage generating circuit includes a back bias/pumping voltage detector for detecting a level difference between a back bias/pumping voltage and a reference voltage, a period controller for controlling a period of an oscillating signal based on the detection result of the back bias/pumping voltage detector, and a pumping unit for pumping the back bias/pumping voltage according to an activation period of the oscillating signal.
