    • Embodiments generally include a method of forming a nonvolatile memory device that contains a resistive switching memory element that has an improved device switching capacity by using multiple layers of variable resistance layers. In one embodiment, the resistive switching element comprises at least three layers of variable resistance materials to increase the number of logic states. Each variable resistance layer may have an associated high resistance state and an associated low resistance state. As the resistance of each variable resistance layer determines the digital data bit that is stored, the multiple variable resistance layers per memory element allows for additional data storage without the need to further increase the density of nonvolatile memory devices. Typically, resistive switching memory elements may be formed as part of a high-capacity nonvolatile memory integrated circuit, which can be used in various electronic devices, such as digital cameras, mobile telephones, handheld computers, and music players.
    • 实施例通常包括形成非易失性存储器件的方法,该非易失性存储器件包含通过使用多层可变电阻层而具有改进的器件开关容量的电阻式开关存储器元件。 在一个实施例中,电阻式开关元件包括至少三层可变电阻材料以增加逻辑状态的数量。 每个可变电阻层可以具有相关联的高电阻状态和相关联的低电阻状态。 由于每个可变电阻层的电阻决定了存储的数字数据位,每个存储元件的多个可变电阻层允许额外的数据存储,而不需要进一步增加非易失性存储器件的密度。 通常,电阻式开关存储器元件可以形成为可用于各种电子设备(例如数码相机,移动电话,手持式计算机和音乐播放器)的大容量非易失性存储器集成电路的一部分。

    • A reversible resistance-switching memory cell has multiple narrow, spaced apart bottom electrode structures. The raised structures can be formed by coating a bottom electrode layer with nano-particles and etching the bottom electrode layer. The raised structures can be independent or joined to one another at a bottom of the bottom electrode layer. A resistance-switching material is provided between and above the bottom electrode structure, followed by a top electrode layer. Or, insulation is provided between and above the bottom electrode structures, and the resistance-switching material and top electrode layer are above the insulation. Less than one-third of a cross-sectional area of each resistance-switching memory cell is consumed by the one or more raised structures. When the resistance state of the memory cell is switched, there is a smaller area in the bottom electrode for a current path, so the switching resistance is higher and the switching current is lower.
    • 可逆电阻切换存储单元具有多个窄间隔开的底部电极结构。 凸起结构可以通过用纳米颗粒涂覆底部电极层并蚀刻底部电极层来形成。 凸起结构可以在底部电极层的底部是独立的或彼此连接的。 电阻切换材料设置在底部电极结构之间和之上,随后是顶部电极层。 或者,在底部电极结构之间和之上提供绝缘,并且电阻切换材料和顶部电极层在绝缘体之上。 每个电阻切换存储单元的横截面积的不到三分之一被一个或多个凸起结构所消耗。 当切换存储单元的电阻状态时,电流路径的底部电极的面积越小,开关电阻越高,开关电流越低。
