ABSTRACT:
A programming voltage is supplied to a control gate of a non-volatile memory cell via a control gate line. A supply voltage is coupled to a first plate of a capacitor and a reference voltage is coupled to a second plate of the capacitor. The supply voltage is then uncoupled from the first plate and the reference voltage is uncoupled from the second plate. Next, the reference voltage is coupled to the first plate to generate the programming voltage on the second plate.
