IBM Makes First Racetrack Memory Chip
holy_calamity writes "For several years, we've followed the progress of IBM's revolutionary 'racetrack' memory, which stores data inside nanowires for several years. Now Big Blue has made the first prototype integrated onto a single chip, using the CMOS processing technique used in commercial chip fabs. It's still a research prototype, but goes some way to validate IBM's claim that the technology could be commercialized."
When I was at IBM they admitted that they mostly used the patents to defend against lawsuits from other companies which were claiming infringement with their own patents.
They were lying to you. IBM licenses their patent portfolio for *billions* of dollars every year. That's not "self defense".
