ABSTRACT:
A depletion type active capacitor may transfer charge from an oscillator to an address line that needs to be boosted for programming. Such a charge pump may be useful in semiconductor memories such as flash memories, EEPROM memories, and NAND EEPROM memories. In some embodiments, relatively low supply voltages can be boosted.
