  • Patent number: 9735357
    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.

    Abstract: One embodiment of the present invention is a semiconductor device at least including an oxide semiconductor film, a gate insulating film in contact with the oxide semiconductor film, and a gate electrode overlapping with the oxide semiconductor film with the gate insulating film therebetween. The oxide semiconductor film has a spin density lower than 9.3×1016 spins/cm3 and a carrier density lower than 1×1015/cm3. The spin density is calculated from a peak of a signal detected at a g value (g) of around 1.93 by electron spin resonance spectroscopy. The oxide semiconductor film is formed by a sputtering method while bias power is supplied to the substrate side and self-bias voltage is controlled, and then subjected to heat treatment.

  • Patent number: 9721634
    Abstract: Magnetic tunnel junction (MTJ) memory bit cells that decouple source line layout from access transistor node size to facilitate reduced contact resistance are disclosed. In one example, an MTJ memory bit cell is provided that includes a source plate disposed above and in contact with a source contact for a source node of an access transistor. A source line is disposed above and in electrical contact with the source plate to electrically connect the source line to the source node. The source plate allows the source line to be provided in a higher metal level from the source and drain contacts of the access transistor such that the source line is not in physical contact with (i.e., decoupled from) the source contact. This allows pitch between the source line and drain column to be relaxed from the width of the source and drain nodes without having to increase contact resistance.
