The negative charge pump of one embodiment comprises an N type switching device to transfer negative charge from its source terminal to its drain terminal. A boot capacitor is coupled to a control terminal of the switching device and forms a boot node between the capacitor and control terminal, boot capacitor to increase a voltage on the boot node. The pump comprises a pull-up device coupled to the switching device, the pull-up device to selectively discharge the boot node. The pump comprises an N type control device coupled to the pull-up device, the control device to selectively enable and disable the pull-up device. The pump comprises an N type pull-down device coupled to the switch device, the pull-up device to selectively precharge the boot node. The pump comprises a pair of N type well biasices coupled to substrate terminals of the switching, pull-up, control, and pull-down devices.
