Magnetic Tunnel Junction의 저항 산포 및 Sense Margin 분석

Abstract

MTJ resistance variation is a serious problem for commercializing STT-MRAM, since it narrows the sense margin between high and low resistance state during read operation. Hence, the study on MTJ resistance variation is essential for improving the sence margin and commercializing STT-MRAM. In this paper, we propose a investigation on MTJ characteristics and resistance variation withcombination of various causes. Also, we analysed the sense margin of MTJ according to the study of MTJ.
