Abstract:
Providing for three-dimensional memory cells having enhanced electric field characteristics and/or memory cells located at broken interconnects is described herein. By way of example, a two-terminal memory cell can be constructed from a layered stack of materials, where respective layers are arranged along a direction that forms a non-zero angle to a normal direction of a substrate surface upon which the layered stack of materials is constructed. In some aspects, the direction can be orthogonal to or substantially orthogonal to the normal direction. In other aspects, the direction can be less than orthogonal to the normal direction. Where an internal angle of the memory cell forms a non-orthogonal angle, an enhanced electric field or current density can result, providing improved switching times and memory performance.
