ABSTRACT:
An apparatus for generating an internal voltage in a semiconductor integrated circuit includes a first voltage generating unit configured to detect a feedback voltage level of a first internal voltage and perform a pumping operation, thereby generating a first internal voltage, and a second voltage generating unit configured to generate a second internal voltage by detecting a feedback voltage level of the second internal voltage, performing level shifting on the detected feedback voltage level, receiving the first internal voltage, and generating the second internal voltage based on the level shifted feedback voltage signal and the received first internal voltage.
