Abstract
Charge pump and discharge circuitry for a non-volatile memory device that splits up the discharge operation into two discharge periods. In a first discharge period, the voltage being discharged (e.g., erase voltage) is discharged through a pair of discharge transistors until the discharging voltage reaches a first voltage level. The path through the pair of discharge transistors is controlled by an intermediate control voltage so that none of the transistors of the pair enter the snapback condition. In the second discharge period, the remaining discharging voltage is fully discharged from the first level through a third discharge transistor.
