IBM Makes First Racetrack Memory Chip 51

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."

    Go back and read the comments on the Dec 2010 [slashdot.org] Slashdot item. A great deal of ire was vented over racetrack memory being in the 10-to-15-year-where's-my-flying-car distant future. And here we sit 12 months later with a functioning CMOS chip. I can't wait to fly around the block.

      And here we sit 12 months later with a functioning CMOS chip that stores only one bit per wire instead of actually being racetrack memory.

      There, fixed that for you.

      • . . . that stores only one bit per wire . . .

        Yes, but imagine a series of tubes built with these wires . . . and there ya' got an Internet, don't ya . . . ?

        Oh, and the US military has funded the aviation industry and built your flying car.

        It's called a cruise missile.

    • Yeah, but then the second page says "the IBM work doesn't yet demonstrate all of the key components that make racetrack memory desirable", so I guess we technically have a flying car, but not the kind that people want.

    People underestimate the value of all the R&D IBM is doing. They spend a lot of money on this kind of research, and they do it seriously. And they don't look for the latest fad to blow the mind of consumers - they build for the long run.

    Ok, their GUIs usually make my eyes bleed and the setup for some of their products is painful (Tivoli anyone?). But IBM is moving forward; their cloud offering, which was a complete joke a few years ago, is getting pretty good. Their stuff does not shine like Apple, it does not integrate like Microsoft, but it works pretty well.

      IBM is the company which gets the most patents awarded. Every single year. Since decades. The don't do research out of goodwill, but for profit. Yes, not just shortsighted, but for the long haul. That's why they still exist. Since 100 years.

      It's hard to compare IBM to Apple, since they target completely different customers: Apple is cosumers, IBM is business.

          I'm not an expert on racetrack memory, but yeah: I'd love to see so much more patents invalidated because of prior art. Today, patents seldom serve their original purpose. 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. Every big player in the business does this (as can be seen in the recent smartphone patent wars), but that's leading off topic...

            Mmm, I think you misunderstood, or the presentation only addressed one sort of patents. IBM makes lots of money from licensing its patents. There is a difference, though, which is that the patents that IBM licenses (by and large, there may be exceptions) are "legitimate". They're real, serious advances in the art which are of real value to their licensees, and not something that any random engineer would come up with off the top of their head when faced with a similar problem. Most of the patents IBM licenses for big bucks are for things like lithography processes, techniques for increasing disk storage density... and this racetrack memory.

            I no longer work for IBM, but I did spend 14 years there and while I have many (many!) other criticisms of the company, I think their approach to patents is a good one.

              I can only say what I've been told. However, I didn't want to create the impression that I despised of IBM's patent politics. The hardly ever attack (troll) with their patents and act very reasonable regarding prior art.

              That said, I'd distinguish between two issues here: #1 trivial patents vs. "real" inventions and #2 patents as a means to drive innovation vs. patents as a war chest to fight off competition. Regarding #1: while I don't have any papers to back up that claim, I've got the impression that IBM'

              If Dave Haynie (at the time with Commodore, I was working for Motorola) would care to contribute to what may be misremembered on my part, I had a conversation with him about how Commodore dealt with IBM. He called it the "Stack-o-Patents (tm)" attack (or was it defense?). Once a year or so, IBMs lawyers would come visit Commodore to discuss licensing issues and bring with them their Stack-o-Patents while getting Commodore's lawyers to bring out theirs, as well.

          IBM may well cite that prior art in their patent application. Contrary to what Slashdot may make you believe, prior art does not invalidate patents. Most patents explicitly list the prior art that led them their. The fact that someone did this with a mercury delay line would in no way invalidate a patent on doing it electronically. This is certainly novel and not obvious. You wouldn't invalidate a patent on a transistor because someone created a switch out of water and gears 100 years ago.

          This is exactly the kind of good research that patents are intended to protect. Companies spending time and money to try and solve a problem no one has solved before in order to advance technology. If IBM truly delivers a memory chip that is an order of magnitude smaller and/or faster than DRAM they deserve the royalties from that patent. We should happily pay it in each chip we buy knowing that the patent system gave them an incentive to push technology.

            I wonder if we will see racetrack vs memristor benchmarks in the future, with the attendant flamewars...

        • That was my first thought to. Of course, it's a reimplementation of mercury delay lines in the same way that an ion drive is a reimplementation of a V2, so it probably does deserve some credit...
        • by Anonymous Coward

          No. No nope no. This is the kind of tech that does deserve a patent. This isn't, "we stuck a clock radio on it." This is a spintronic device that stores data sequentially. The physics is different, the implementation is different. The fact that the output is the same has nothing to do with the originality of the device.

          Yeah, but most of IBM's patents are the good ones. Won't say all — someone's bound to find a counterexample — but the vast majority are in areas where patents work fine and have always worked. (For example, if you're doing advanced chip design then you're working in an area where there masses of IBM patents, mostly expired.)

          Patents are a problem only when they are unclear, over-broad, and insufficiently innovative. Alas, too many in the computing area are like that, but IBM's seem to be much les

      Definitely. Tivoli is such a pain to setup. TDI, TAM, iTIM, TEM...even the middleware is a nightmare of an install for a setup. Having to use Xming/Reflections for middleware component installation on an AIX box is just annoying....

        If you want to have a surreal experience, visit an IBM conference or trade show (such as the IBM Tech University) and go for a drink with a bunch of Tivoli consultants. Yep, people who have spent their days in Tivoli, for years. They are a special breed, very resilient.

    • Heh heh. The setup for Tivoli is so bad that you can pay them millions just to get it installed... and then you have to run Tivoli. Still pretty amazing, but boy is it obfuscated.
