Physics-based compact modeling framework for state-of-the-art and emerging STT-MRAM technology

A comprehensive compact modeling framework coupling quantum transport with magnetic dynamics has been developed for state-of-the-art and emerging STT-MRAMs. After validation with numerical simulation and experimental results, various transistor-MRAM cell architectures have been studied for their performance and variability. SOT-assisted MRAMs are found to have significant improvement on Erase time over conventional STT-MRAMs.
