A non-volatile memory device comprises a substrate with the dielectric layer formed thereon. A control gate and a floating gate are then formed on top of the dielectric layer. Accordingly, a non-volatile memory device can be constructed using a single poly process that is compatible with conventional CMOS processes. In addition, an assist gate, or assist gates are formed on the dielectric layer next to and between the control gate and floating gate respectively. The assist gates are used to form inversion diffusion regions in the substrate. By using the assist gates to form inversion diffusion regions, the overall size of the device can be reduced, which can improve device density.
