Abstract
A memory device that selectably exhibits first and second logic levels. A first conductive material has a first surface with a first memory layer formed thereon, and a second conductive material has a second surface with a second memory layer formed thereon. A connective conductive layer joins the first and second memory layers and places the same in electrical contact. The structure is designed so that the first memory layer has a cross-sectional area less than that of the second memory layer.
