Internal voltage generating circuit
An internal voltage generating circuit includes a drive signal generating unit, a drive signal controlling unit, and a driving unit. The drive signal generating unit is configured to compare an internal voltage with first and second reference voltages and generate a first pull-up drive signal and a first pull-down drive signal. The drive signal controlling unit is configured to buffer the first pull-up drive signal and the first pull-down drive signal and generate a second pull-up drive signal and a second pull-down drive signal, wherein the second pull-up drive signal and the second pull-down drive signal are deactivated when the first pull-up drive signal and the first pull-down drive signal are activated. The driving unit is configured to drive the internal voltage in response to the second pull-up drive signal and the second pull-down drive signal.
