ABSTRACT:
A DMOS device is provided which is equipped with a floating gate having a first and second electrode in close proximity thereto. The floating gate is separated from one of the first and second electrodes by a thin layer of dielectric material whose dimensions and composition permit charge carriers to tunnel through the dielectric layer either to or from the floating gate. This tunneling phenomenon can be used to create a threshold voltage that may be adjusted to provide a precise current by placing a voltage between a programming electrode and the body/source and gate electrode of the device.
