Abstract :
An efficient Vpp generator with a charge recycle pump and a charge transfer pump have been proposed. The charge recycle operation can reduce the Vpp generating current by 38% without decreasing the Vpp supply current. The charge transfer operation enables the generation of the Vpp supply current at over the 2/spl middot/Vcc level. These techniques are highly effective in low voltage DRAMs.
