摘要:
Thin film 1S1R bitcells incorporating a barrier between selector and memory elements. Devices incorporating such bitcells and methods of forming such bitcells are also described. In embodiments, the selector and memory element is each a dielectric material, and advantageously a metal oxide. Between the selector and memory elements is a barrier, which is to reduce intermixing and/or reaction of selector material and memory material. Addition of a barrier layer having suitable material properties into the 1S1R stack may extend the operating lifetime of a bitcell incorporated the stack by resisting intermixing and/or reaction of the selector and memory thin film materials driven by thermal and/or electric field stresses experienced by a bitcell during operation. In embodiments, a barrier layer may include one or more material layers having a composition distinct from the material composition(s) of the selector and memory elements.
摘要(中):
薄膜1S1R位单元在选择器和存储器元件之间包含屏障。 还描述了包含这种位单元的器件以及形成这种位单元的方法。 在实施例中,选择器和存储器元件各自是电介质材料,并且有利地是金属氧化物。 在选择器和存储器元件之间是屏障,其用于减少选择器材料和存储器材料的混合和/或反应。 向1S1R叠层中添加具有合适材料特性的阻挡层可以通过抵抗选择器和存储器薄膜材料的混合和/或反应来延长并入叠层中的位单元的工作寿命,所述选择器和存储器薄膜材料由 操作过程中的位单元。 在实施例中,阻挡层可以包括具有与选择器和存储器元件的材料组成不同的组成的一个或多个材料层。
