Abstract

The history of MRAM development, including the toggling method and future perspectives were reviewed. Also, the giant TMR effect reported quite recently for MgO barrier junction and Heusler electrode junction was introduced In addition, spin dynamics, which are closely related with high speed and large capacity MRAM technologies, was shown. Especially, the enhancement of Gilbert damping constant was introduced.
