Abstract:
A method for continuously regulating an output voltage of a charge pump of a non-volatile memory to a target voltage wherein said non-volatile memory comprises a regulator comprising a first regulator sub-circuit and a second regulator sub-circuit, the method comprising the steps of:(a) regulating said output voltage to said target voltage with said first regulator sub-circuit in conjunction with a single reference voltage for a first period of time;(b) disabling said first regulator sub-circuit for a second period of time at the end of said first period of time; and(c) regulating said output voltage to said target voltage, at the end of said second period of time, with said second regulator sub-circuit in conjunction with said reference voltage for a third period of time while said first regulator sub-circuit is disabled.
