  • Patent number: 10608180
    Abstract: Providing for a two-terminal memory cell having intrinsic current limiting characteristic is described herein. By way of example, the two-terminal memory cell can comprise a particle donor layer having a moderate resistivity, comprised of unstable or partially unstable metal compounds. The metal compounds can be selected to release metal atoms in response to an external stimulus (e.g., an electric field, a voltage, a current, heat, etc.) into an electrically-resistive switching medium, which is at least in part permeable to drift or diffusion of the metal atoms. The metal atoms form a thin filament through the switching medium, switching the memory cell to a conductive state. The moderate resistivity of the particle donor layer in conjunction with the thin filament can result in an intrinsic resistance to current through the memory cell at voltages above a restriction voltage, protecting the memory cell from excessive current.

  • Patent number: 10134984
    Abstract: Providing an electrode for a two-terminal memory device is described herein. By way of example, the electrode can comprise a contact surface that comprises at least one surface discontinuity. For instance, the electrode can have a gap, break, or other discontinuous portion of a surface that makes electrical contact with another component of the two-terminal memory device. In one example, the contact surface can comprise an annulus or an approximation of an annulus, having a discontinuity within a center of the annulus, for instance. In some embodiments, a disclosed electrode can be formed from a conductive layer deposited over a non-continuous surface formed by a via or trench in an insulator, or over a pillar device formed from or on the insulator.
