Abstract
An internal voltage generator is capable of supplying a stable internal voltage regardless of an unstable external voltage. The internal voltage includes a first level detecting unit configured to detect a voltage level of the internal voltage and output an output power detecting signal, an oscillating unit configured to produce a periodical signal in response to the output power detecting signal, a second level detecting unit configured to detect a voltage level of an external voltage and output a driving power detecting signal, a dividing unit configured to selectively divide the periodical signal in response to the driving power detecting signal and output a divided signal, and a charge pumping unit configured to provide the internal voltage by pumping the external voltage in response to the divided signal.
