    摘要: 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.

    摘要: This disclosure provides a method of fabricating a semiconductor device layer and associated memory cell structures. By performing a surface treatment process (such as ion bombardment) of a semiconductor device layer to create defects having a deliberate depth profile, one may create multistable memory cells having more consistent electrical parameters. For example, in a resistive-switching memory cell, one may obtain a tighter distribution of set and reset voltages and lower forming voltage, leading to improved device yield and reliability. In at least one embodiment, the depth profile is selected to modulate the type of defects and their influence on electrical properties of a bombarded metal oxide layer and to enhance uniform defect distribution.

    摘要: Non-volatile resistive-switching memories formed using anodization are described. A method for forming a resistive-switching memory element using anodization includes forming a metal containing layer, anodizing the metal containing layer at least partially to form a resistive switching metal oxide, and forming a first electrode over the resistive switching metal oxide. In some examples, an unanodized portion of the metal containing layer may be a second electrode of the memory element.

    摘要: Selector devices that can be suitable for memory device applications can have low leakage currents at low voltages to reduce sneak current paths for non selected devices, and high leakage currents at high voltages to minimize voltage drops during device switching. In some embodiments, the selector device can include a first electrode, a tri-layer dielectric layer, and a second electrode. The tri-layer dielectric layer can include a high leakage dielectric layer sandwiched between two lower leakage dielectric layers. The low leakage layers can function to restrict the current flow across the selector device at low voltages. The high leakage dielectric layer can function to enhance the current flow across the selector device at high voltages.
