摘要

通过考虑开关材料的微观结构特性和与开关过程相关的物理效应,对氧化基RRAM的开关行为和操作机制等基础物理问题提出了新的物理见解。基于新的物理见解,开发了基于HfOx和taox的RRAM平台,包括仿真工具和紧凑模型,能够再现RRAM的基本电气和微观特性,并在器件和电路系统之间架起桥梁,满足器件-电路-系统协同设计和优化的要求。

Oxide-based RRAM: Requirements and challenges of modeling and simulation
New physical insights on the underlying physics from switching behaviors to operating mechanisms of oxide-based RRAM are presented by taking the microstructure nature of switching materials and correlated physical effects with switching process into account. Based on the new physical insights, a platform for HfOx- and TaOx-based RRAM including simulation tools and compact models is developed, which is able to reproduce the essential electrical and microscopic characteristics of RRAM and bridge the link between device and circuit systems, meeting the requirements of device-circuit-system co-design and optimization.
