Abstract:
A multilayer matrix-addressable logic device or processor device with two or more individually matrix-addressable stacked thin film of an active material which under the influence of an electric current or an electric field can attain two or more physically or chemically distinct detectable stable metastable states wherein each are assigned respective logical values and which can transfer from a state of this kind to another, wherein the active material in each layer is provided between a first electrode set and a second electrode set wherein each comprises substantially mutually parallel striplike electrodes, such that the electrodes in the first electrode set constitute the rows in a substantially orthogonal array, wherein the intersections between the electrodes in the array define logic cells in the layer of active material and wherein the stacked layers of active material are provided on a common supporting substrate, and including:a separation layer between each of said adjacent stacked layers of active material, whereby to provide a stacked array of modules on the common substrate and sequentially provide a plurality of such array of modules stacked one above the other with the material from which the separation layer is formed being conductive and providing separations.
