Abstract
A semiconductor memory device using silicon-rich amorphous silicon alloy material memory elements that are electrically programmable by means of current induced conductivity comprises a layer (,) of the alloy material on opposing sides of which sets of input and output contacts (,) are provided, and discrete conductive elements (,) within the layer which serve as nodes and define programmable conductive paths between input and output contacts to create a three dimensional memory network. The conductive elements can be arranged at one or more levels within the thickness of the alloy layer and preferably are of defined shape forming a predetermined 2D array at each level.
