A memory device and a method of fabrication are provided. The memory device includes a semiconductor substrate and a charge trapping dielectric stack disposed over the semiconductor substrate. A gate electrode is disposed over the charge trapping dielectric stack, where the gate electrode electrically defines a channel within a portion of the semiconductor substrate. The memory device includes a pair of bitlines, where the bitlines have a lower portion and a substantially trapezoidal shaped upper portion. |
