A*STAR researchers shed light on STT-RAM chip production temperature trade-offs

Researchers from A*STAR have posted an interesting study about STT-RAM production process. In particular, they say that it’s already known that the annealing temperature controls the change in resistance between parallel and anti-parallel magnetizations. The higher the annealing temperature, the better larger the resistance change – but if the temperature is too high it drops.
The researchers now looked at an entire cell, and found out that the annealing temperature that yielded the maximum resistance variation exceeded the temperature necessary for maximum thermal stability.
