Abstract
In one aspect, a charge pump output of a charge pump is coupled to a capacitor of a voltage shifter. The output of the voltage shifter causes pump control logic to enable the charge pump. In another aspect, a transistor in saturation has a drain terminal coupled to a charge pump output and a source terminal coupled to an output mode providing a word line read voltage.
