Abstract :
This paper describes the working principle of thermally assisted MRAM extending the downsize scalability of MRAM and introducing new functionalities particularly useful for security applications. Ultimately, STT switching assisted by thermally induced anisotropy reorientation can be used in MTJ with perpendicular magnetic anisotropy to obtain ultimate downsize scalability with reduced power consumption.
