Internal voltage converter for low operating voltage semiconductor memory

摘要

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.
