Abstract
An internal voltage generating apparatus includes: a voltage detector that detects the level of the internal voltage and outputs a fixed level detection signal and a variable level detection signal. An oscillation controller generates an oscillation enable signal according to whether the fixed level detection signal and the variable level detection signal are enabled. An internal voltage generator generates the internal voltage in response to the oscillation enable signal.
