ABSTRACT:
A three-dimensional tunnel memory device includes a multilayer Langmuir-Blodgett film wherein each layer can store or carry an electric charge. Charges are introduced into one side of the film in a time sequence corresponding to the information to be carried. An electric field is applied between the faces of the film to cause the charge stored by any layer to be transferred to the adjacent layer, and for thus reading out the sequence of charges stored by the film. The multilayer Langmuir-Blodgett film includes memory unit cells each comprising Langmuir-Blodgett films formed, respectively, of different kinds of organic compounds and contacting each other. Electric fields of different magnitudes are applied, respectively, to the film constituting each memory unit cell thereby allowing the stored charge in each film constituting the memory unit cell to hop the tunnel barrier.
