ABSTRACT:
An internal voltage generating circuit includes a first detector that compares an internal voltage and a first reference voltage to output a first detection signal. A second detector compares a supply voltage and a second reference voltage to output a second detection signal. A loop selection oscillator performs an oscillation operation in response to the first detection signal, selects a first loop or a second loop for performing the oscillation operation in response to the second detection signal, and outputs an oscillation signal. A charge pump performs a pumping operation according to the output of the loop selection oscillator and generates the internal voltage.
