Abstract
An internal voltage generator includes: a detection unit configured to detect a level of an internal voltage in comparison to a reference voltage; a first driving unit configured to discharge an internal voltage terminal, through which the internal voltage is outputted, in response to an output signal of the detection unit; a current detection unit configured to detect a discharge current flowing through the first driving unit; and a second driving unit configured to charge the internal voltage terminal in response to an output signal of the current detection unit.
