  • Publication number: 20180261764
    Abstract: A three-terminal non-volatile multi-state memory device based on mobile ion induced electrical resistivity change is provided. The three-terminal non-volatile multi-state memory device-includes a substrate having a first electrode and a second electrode therein. The three-terminal non-volatile multi-state memory device further includes a mobile ion including resistor layer disposed over the first electrode, the second electrode, and part of the substrate. The three-terminal non-volatile multi-state memory device also includes a third electrode formed over the mobile ion including resistor layer. The three-terminal non-volatile multi-state memory device provides multi-level states determined by an electrical resistivity of the mobile ion including resistor layer which changes the electrical resistivity based on the mobile ton concentration in the material.

  • Publication number: 20180247181
    Abstract: A method for updating the resistance of a controllable resistance element includes determining an amount of resistance change for the controllable resistive element. A charge difference for a battery is determined corresponding to the resistance change for the controllable resistive element. The battery is charged or discharged to effect the resistance change in the controllable resistive element.

  • Publication number: 20180247179
    Abstract: A controllable resistive element and method for updating the resistance of the same includes a state device configured to provide a voltage-controlled resistance responsive to a voltage input. A battery is configured to apply a voltage to the voltage input of the state device based on a charge stored in the battery. A write device is configured to charge the battery responsive to a write signal. An erase device is configured to discharge the battery responsive to an erase signal.
