  • Memory devices, methods of storing and reading data, SMM junctions, and methods of preparing alumina substrates
    Patent number: 9183927
    Abstract: Various aspects of the invention provide memory devices, methods of storing and reading data, and silver/molecular-layer/metal (SMM) junctions. One aspect of the invention provides a memory device including a plurality of SMM junctions and an electrical structure configured to permit application of electricity across one or more of the plurality of SMM junctions. Another aspect of the invention provides a method of storing data on a memory device including a plurality of SMM junctions. The method includes applying electrical energy across a subset of the SMM junctions to switch the junction to a more conductive state. Another aspect of the invention provides an SMM junction including a silver layer, a copper layer, and a molecular layer positioned between the silver layer and the copper layer.
