ABSTRACT:
A pumping voltage generating apparatus includes a detection signal generating unit that generates a detection signal when a pumping voltage is lower than a reference value. A pumping unit elevates a first external voltage by a second external voltage to be output as the pumping voltage, in response to the detection signal. In this case, the second external voltage is lower than the first external voltage.
