Abstract:
A memory storage and retrieval device, comprising:(a) an electrically conductive first electrode; (b) an electrically conductive second electrode; and (c) a layer stack intermediate said first and second electrodes, said layer stack comprising: (d) at least one active aver comprising at least one polymer material with variable electrical conductivity, said electrical conductivity of said at least one active layer is reversibly varied upon introduction of charged species thereinto and removed of said charged species therefrom; and (e) at least one passive layer comprised of a material for varying said electrical conductivity of said at least one active layer upon application of an electrical potential difference between said first and second electrically conductive electrodes, said at least one passive layer is comprised of a said material for reversibly donating said charged species to and accepting said charged species from said active layer.
