摘要

开发可扩展且用户友好的SPICE模型是探索自旋传递扭矩MRAM (STT-MRAM)潜力的关键方面。本文提出了一种自包含磁隧道结(MTJ) SPICE模型,该模型可以根据用户自定义的输入参数(如自由层的长度、宽度和厚度)再现真实的MTJ特性。使用该模型,可以在不同的技术节点上以最小的努力进行平面内和垂直mtj的可扩展性研究,这将该模型与大多数先前报道的模型区别开来。

A technology-agnostic MTJ SPICE model with user-defined dimensions for STT-MRAM scalability studies
The development of a scalable and user-friendly SPICE model is a key aspect of exploring the potential of spin-transfer torque MRAM (STT-MRAM). A self-contained magnetic tunnel junction (MTJ) SPICE model is proposed in this work which can reproduce realistic MTJ characteristics based on user-defined input parameters such as the free layer's length, width, and thickness. Using the propose model, scalability studies of both in-plane and perpendicular MTJs can be performed across different technology nodes with minimal effort, which differentiates this model from most previously reported models.
