Abstract
A recursive voltage booster circuit is provided for generating a boosted output voltage to be higher than the low power supply potential to drive control gates via row decoder circuits and wordlines in an array of Flash EEPROM memory cells during a Read mode of operation. The voltage booster circuit includes a plurality of recursively connected boosting stages. The lower power supply potential has a voltage of +2.0 volts or lower. The boosted output voltage is significantly higher than what is traditionally available so as to enable reading of Flash EEPROM memory cells in a very low power supply voltage environment.
