π€ What Is Spintronic Memory?
Think of electrons as tiny spinning magnets that remember which way they point! Traditional memory uses electric charge (trillions of electrons moving). Spintronics uses the spin direction of just a few electrons - up β or down β. Result: 1000x more efficient, never loses data when powered off!
It's already in your pocket! Samsung and Apple use MRAM for instant-on capability. Self-driving cars use it because it survives cosmic radiation. NASA uses it in spacecraft. And it will power future quantum computers!
