    Abstract: This disclosure provides a nonvolatile memory device and related methods of manufacture and operation. The device may include one or more resistive random access memory (ReRAM) approaches to provide a memory device with more predictable operation. In particular, the forming voltage required by particular designs may be reduced through the use of a barrier layer, a reverse polarity forming voltage pulse, a forming voltage pulse where electrons are injected from a lower work function electrode, or an anneal in a reducing environment. One or more of these techniques may be applied, depending on the desired application and results.

    Abstract: According to various embodiments, a resistive-switching memory element and memory element array that uses a bipolar switching includes a select element comprising only a single diode that is not a Zener diode. The resistive-switching memory elements described herein can switch even when a switching voltage less than the breakdown voltage of the diode is applied in the reverse-bias direction of the diode. The memory elements are able to switch during the very brief period when a transient pulse voltage is visible to the memory element, and therefore can use a single diode per memory cell.

    Abstract: Provided are resistive switching cells and methods of using such cells for controlling operation of liquid crystal display (LCD) cells in LCD devices. A resistive switching cell has two electrodes formed from transparent conductive oxides, such as indium oxide, indium tin oxide, or zinc oxide. One electrode may be connected to a LCD cell thereby forming an in series connection between the resistive switching cell and LCD cell. The other electrode may be used to power the LCD cell through the resistive switching cell. The resistive switching cell also includes a resistive switching layer disposed between the two electrodes. When the resistive switching layer is in its low resistive state, the LCD cell is subjected to an operating potential and produces light. However, when the resistive switching layer is in its high resistive state, the LCD cell is not subjected to the operating potential and does not produce light.

    Abstract: Provided are resistive switching memory cells and method of forming such cells. A memory cell includes a resistive switching layer disposed between two buffer layers. The electron barrier height of the material used for each buffer layer is less than the electron barrier height of the material used for the resistive switching layer. Furthermore, the thickness of each buffer layer may be less than the thickness of the resistive switching layer. The buffer layers reduce diffusion between the resistive switching layer and electrodes. Furthermore, the buffer layers improve data retention and prevent unintentional resistive switching when a reading signal is applied to the memory cell. The reading signal uses a low voltage and most of the electron tunneling is blocked by the buffer layers during this operation. On the other hand, the buffer layers allow electrode tunneling at higher voltages used for forming and switching signals.

    Abstract: A resistive-switching memory (ReRAM cell) has a current-limiting electrode layer that combines the functions of an embedded resistor, an outer electrode, and an intermediate electrode, reducing the thickness of the ReRAM stack and simplifying the fabrication process. The materials include compound nitrides of a transition metal and one of aluminum, boron, or silicon. In experiments with tantalum silicon nitride, peak yield in the desired resistivity range corresponded to ˜24 at % silicon and ˜32 at % nitrogen, believed to optimize the trade-off between inhibiting TaSi2 formation and minimizing nitrogen diffusion. A binary metal nitride may be formed at one or more of the interfaces between the current-limiting electrode and neighboring layers such as metal-oxide switching layers.
