Victor Karpov, Dipesh Niraula, Ilya Karpov, Roza Kotlyar

摘要:

本文提出了一种唯象的电阻式随机存取存储器(RRAM)理论,描述了它们的电流-电压特性。我们的方法遵循的方法,热力学理论开发的硫族化物存储器和阈值开关,在很大程度上独立于他们的微观细节。它解释了,没有可调参数,如域的灯丝形成和开关,电压无关的电流在SET和电流无关的电压在switching制度,设置和复位电压之间的关系,灯丝电阻独立于其长度等功能,此外,它表示观察到的功能,通过材料和电路参数,从而铺平了道路,设备的改进。

英文摘要:

We present a phenomenological theory of filamentary resistive random access memory (RRAM) describing the commonly observed features of their current-voltage characteristics. Our approach follows the approach of thermodynamic theory developed earlier for chalcogenide memory and threshold switches and largely independent of their microscopic details. It explains, without adjustable parameters, such features as the domains of filament formation and switching, voltage independent current in SET and current independent voltage in RESET regimes, the relation between the set and reset voltages, filament resistance independent of its length, etc. Furthermore, it expresses the observed features through the material and circuitry parameters thus paving a way to device improvements.
