摘要

开发了一种三维动力学蒙特卡罗(kMC)模拟工具,用于研究允许Ni/HfO2/Si器件作为非易失性存储器工作的电阻开关(RS)过程。该模拟器采用了大量的实验数据,它可以再现设备在成形、设置和复位过程中的电流、周期到周期的可变性以及与RS操作的随机性相关的其他特性。深入分析了不同RS循环下导电丝的演变,以及导电丝的密度和电阻。

A Kinetic Monte Carlo Simulator to Characterize Resistive Switching and Charge Conduction in Ni/HfO2/Si RRAMs
A 3D kinetic Monte Carlo (kMC) simulation tool has been developed to study the resistive switching (RS) processes that allow Ni/HfO2/Si devices to work as non-volatile memories. The simulator is tuned with numerous experimental data and it can reproduce the device current in forming, set and reset processes, the cycle-to-cycle variability and other characteristics linked to the stochasticity of RS operation. The evolution of conductive filaments (CFs) for different RS cycles is analyzed in depth, as well as the filaments density and resistance.
