I have never heard of MRAM before this but it addresses the only issues I have with Flash memory (used as RAM most frequently and now more often as hard drives). Flash memory has a limit in how many times it can be written over. Most people using it for taking pictures or whatever will never see effects of this but Flash memory in a hard drive would be apparent, spread over a couple of years, of course. So MRAM addresses that. It also addresses the issue of RAM's inability to keep data while powered down. MRAM is also faster than RAM. However, it will take a while before it is cheap enough for someone like me to use it. Still, quite exciting.(via Engadget)
