Abstract:
1. An internal voltage generating circuit comprising: a drive signal generating unit 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; a drive signal controlling unit 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; and a driving unit configured to drive the internal voltage in response to the second pull-up drive signal and the second pull-down drive signal, wherein the first pull-up drive signal is activated when the internal voltage has a lower level than the first reference voltage.
