Abstract
The present invention provides an internal voltage converter that comprises a voltage down converter which receives an external voltage and provides an intermediate voltage that is stable and lower than the external voltage. The intermediate voltage is used to operate a clock signal generator and a timing controller that produces a timing signal. The regulator also includes a booster that receives the timing signal and the external voltage, and outputs a boosted voltage that is of a lower level than in the prior art. The regulator also includes a voltage source that receives the boosted voltage and the external voltage, and outputs the device's internal operating voltage for operating it.

A voltage regulator circuit for operating a semiconductor memory device comprising:
- a voltage down converter for receiving an external voltage and thereby providing an intermediate voltage;
- a timing pulse generator for receiving the intermediate voltage and generating a timing signal;
- a booster for receiving the timing signal and the external voltage, the booster thereby outputting a boosted voltage;
- and
- a voltage source receiving the boosted voltage and the external voltage, and thereby outputting a source voltage for operating the semiconductor memory device.
