- Abstract
- Nanoscale metal-oxide-nitride-oxide-silicon (MONOS) NAND flash memory devices with a metal spacer layer were designed to increase the fringing field and the coupling ratio of the control gate and to decrease the coupling interference between the cells. The simulation results showed that the drain current and the threshold voltage shift of the MONOS NAND flash memory devices utilizing a metal spacer increased due to the increase of the fringing field and the coupling ratio. The electrical field on the channel surface of the memory devices with a metal spacer layer increased, indicative of the achievement of the maximum fringing field effect, resulting in an increase of the drain current. The simulation results showed that the coupling interference for the memory devices utilizing a metal spacer decreased resulting from the shielding of the electric field between neighboring cells.
