    • Provided are resistive random access memory (ReRAM) cells having Schottky barriers and methods of fabricating such ReRAM cells. Specifically, a ReRAM cell includes two Schottky barriers, one barrier limiting an electrical current through the variable resistance layer in one direction and the other barrier limiting a current in the opposite direction. This combination of the two Schottky barriers provides current compliance during set operations and limits undesirable current overshoots during reset operations. The Schottky barriers' heights are configured to match the resistive switching characteristics of the cell. Conductive layers of the ReRAM cells operable as electrodes may be used to form these Schottky barriers together with semiconductor layers. These semiconductor layers may be different components from a variable resistance layer and, in some embodiments, may be separated by intermediate conductive layers from the variable resistance layers.
    • 提供了具有肖特基势垒的电阻随机存取存储器(ReRAM)单元和制造这种ReRAM单元的方法。 具体来说,ReRAM单元包括两个肖特基势垒,一个势垒限制了沿一个方向通过可变电阻层的电流,另一个势垒限制了相反方向上的电流。 两个肖特基势垒的这种组合在设置操作期间提供电流兼容性,并在复位操作期间限制不期望的电流过冲。 肖特基势垒的高度配置为匹配电池的电阻开关特性。 可用作电极的ReRAM单元的导电层可以用于与半导体层一起形成这些肖特基势垒。 这些半导体层可以是与可变电阻层不同的部件,并且在一些实施例中可以由可变电阻层的中间导电层分离。

    • A method of forming a nonvolatile memory device that contains a resistive switching memory element that has an improved device switching performance and lifetime, due to the addition of a current limiting component disposed therein. The current limiting component comprises at least one layer of resistive material configured to improve the switching performance and lifetime of the formed resistive switching memory element. The electrical properties of the formed current limiting layer, or resistive layer, are configured to lower the current flow through the variable resistance layer during the logic state programming ("set" and "reset") steps by adding a fixed series resistance in the formed resistive switching memory element found in the nonvolatile memory device. Resistive switching memory elements may be formed as part of a high-capacity nonvolatile memory integrated circuit used in various electronic devices, such as digital cameras, mobile telephones, handheld computers, and music players.
