Abstract:
An embodiment of the present invention is directed to a memory cell. The memory cell includes a first trench formed in a semiconductor substrate and a second trench formed in said semiconductor substrate adjacent to said first trench. The first trench and the second trench each define a first side wall and a second sidewall respectively. The memory cell further includes a first storage element formed on the first sidewall of the first trench and a second storage element formed on the second sidewall of the second trench.
