It's been a long, hard slog for MRAM.

As a resistance-based memory, MRAM must scale by increasing its level resistance. For a given resistance-area product, this can be achieved by directly shrinking the MTJ. This is similar to the PCM approach. Still I don't know why it hasn't be pursued more actively.

I think getting well defined states in small, isolated magnetic elements is more difficult than once thought.

Also, as the elements gets smaller, they become more thermally unstable.

Also the MR ratio is too small, even the transistor Ion range will cover it up.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
