  • Patent number: 9269896
    Abstract: Provided are resistive random access memory (ReRAM) cells and methods of fabricating thereof. A stack including a defect source layer, a defect blocking layer, and a defect acceptor layer disposed between the defect source layer and the defect blocking layer may be subjected to annealing. During the annealing, defects are transferred in a controllable manner from the defect source layer to the defect acceptor layer. At the same time, the defects are not transferred into the defect blocking layer thereby creating a lowest concentration zone within the defect acceptor layer. This zone is responsible for resistive switching. The precise control over the size of the zone and the defect concentration within the zone allows substantially improvement of resistive switching characteristics of the ReRAM cell. In some embodiments, the defect source layer includes aluminum oxynitride, the defect blocking layer includes titanium nitride, and the defect acceptor layer includes aluminum oxide.

  • Patent number: 9105669
    Abstract: A new type of Metal Oxide Semiconductor (MOS) transistor that works on the basis of the Quantum Interference Depression (QID) effect is disclosed. QID occurs inside an n-type semiconductor source-drain electrode of special geometry. Due to QID the Fermi level of said semiconductor increases locally inside the source drain electrode, thereby creating a localized potential energy barrier in the path of electrons moving from source to drain regions. The height of the barrier depends on the degree of QID. QID is in turn regulated by the gate voltage via the charge depletion and hence change in effective dimensions of the special geometry of the semiconductor electrode. A gate voltage modulated potential energy barrier and is thus formed whereby current in said MOS transistor is controlled.
