Abstract
An internal power supply generating circuit has a control circuit for controlling a control node voltage of a driver circuit thereof. During an overdrive duration, the control node voltage is set at an appropriate level of an operation range by controlling the control node voltage by the control circuit. By setting the control node voltage at the appropriate level, the internal power supply generating circuit can supply an internal power-supply voltage without a dead band after the overdrive duration. With this structure, the internal power supply generating circuit without the dead band can be obtained and a semiconductor device operable at a high speed comprising the internal power supply generating circuit can be obtained.
