Yep, had read about that a few months ago.
See my text on the website:

MRAM is described (brief) at the end. Also has
a link to a Motorola article!

 Subject: Magnetic Memory making a comeback?
 There is a _new_ type of memory being developed called MRAM,
 which uses magnetic fields to store data.
 An interesting quote from the article (to bring it on-topic):
 "Magnetic fields have been used to store data since time immemorial,"
 he joked. "We were using it in the early 1960s and 1950s."
