These things are more accurate called "spintronics." They are very different from conventional magnetic recording technologies.

- bippingchip 4y agoHaving worked closely on the circuit side of things with folks doing research on spintronics and STT-MRAM devices: it’s going to be a very long time still before this can replace embedded SRAM. The MRAM itself can be made quite small, but you still need an access transistor and wrote currents are still too high, which means very big transistors, which then dominate memory area… Also, writing is much slower compared to SRAM. It’s a very nice embedded flash replacement though…
