Summary :

A two-phase boosted voltage (VPP) generator circuit was proposed for use in giga-bit DRAMs. It reduced the maximum gate oxide voltage of pass transistor and the lower limit of supply voltage to VPP and VTN respectively while those for the conventional charge pump circuit are VPP+VDD and 1.5 VTN respectively. Also the pumping current was increased in the new circuit.
