Non-volatile memory device
First Claim
1. A semiconductor device comprising:
- a substrate region;
a source region formed in the substrate region;
a drain region formed in the substrate region and separated from the source region by a channel region;
a first gate overlaying a first portion of the channel and separated therefrom via a first insulating layer; and
a second gate overlaying a second portion of the channel and separated therefrom via a second insulating layer;
wherein said first portion of the channel and said second portion of the channel do not overlap.

Abstract
A non-volatile memory device (hereinafter alternatively referred to device) includes a guiding gate that extends along a first portion of the device'"'"'s channel length and a control gate that extends along a second portion of the device'"'"'s channel length. The first and second portions of the channel length do not overlap. The guiding gate, which overlays the substrate above the channel region, is insulated from the semiconductor substrate in which the device is formed via an oxide layer. The control gate, which also overlays the substrate above the channel region, is insulated from the substrate via an oxide-nitride-oxide layer. The device includes a source terminal, a drain terminal, a guiding gate terminal, a control gate terminal, and a substrate terminal coupled to the semiconductor substrate in which the device is formed.
