ABSTRACT:
System and method for controlling voltage in a non-volatile memory system is provided. The system includes a voltage regulator that monitors an output voltage (VDD) and a mirror voltage (Vmirror). When the voltage VDD is greater than the voltage Vmirror beyond a threshold value, a control signal turns off a control transistor, which prevents the voltage VDD to increase beyond a certain value. The method includes comparing an output voltage (VDD) with a mirror voltage (Vmirror); and generating a control signal to turn off a control transistor if the voltage VDD is greater than the voltage Vmirror.
