An apparatus for using feedback to set a floating gate to a desired voltage during a set mode is disclosed. The apparatus includes a floating gate, a first and second tunnel device formed respectively between the floating gate and a first and second electrode, a first circuit coupled to the floating gate for comparing the voltage on the floating gate to a third voltage and for generating an output voltage at an output terminal, and a feedback circuit coupled between the output terminal and the floating gate. The feedback circuit includes the first tunnel device and a third tunnel device for causing the floating gate voltage to be modified as a function the output voltage until the floating gate voltage, the third voltage and the output voltage are approximately equal. |
