HP Reports Memory Resistor Breakthrough

andy1307 writes "Hewlett-Packard scientists on Thursday will report advances demonstrating significant progress in the design of memristors, or memory resistors. The researchers previously reported in The Proceedings of the National Academy of Sciences that they had devised a new method for storing and retrieving information from a vast three-dimensional array of memristors. The scheme could potentially free designers to stack thousands of switches on top of one another in a high-rise fashion, permitting a new class of ultra-dense computing devices even after two-dimensional scaling reaches fundamental limits."

      According to TFA, the intended use for this is memory devices (possibly a follow-on to flash memory). Since it can retain it's state even without power, it would seem that this would result in an extremely low power device which should produce very low heat.

      Yes. Memristors don't require that power be applied in order to retain memory state. Heat might limit write and retrieval rate, but it wouldn't limit the number of layers. I suspect that it might make heat pipes built into the memory boards to be a highly desirable option, but that would be to enable faster access, not to allow a greater number of layers.

      It's more than that. This could have huge implications for no-power flash storage, and it has lower power requirements than the phase-change memory that is currently the top dog. I'm also curious about the 'data processing' blurb in TFA:

      "They are simpler than today’s semiconducting transistors, can store information even in the absence of an electrical current and, according to a report in Nature, can be used for both data processing and storage applications."

      "He said the company could have a competitor to flash memory in three years that would have a capacity of 20 gigabytes a square centimeter."

      "The new material offers an approach that is radically different from a promising type of storage called “phase-change memory” being pursued by I.B.M., Intel and other companies. In a phase-change memory, heat is used to shift a glassy material from an amorphous to a crystalline state and back. The switching speed of these systems is slower and requires more power, the H.P. scientists say."

      I suspect that it might make heat pipes built into the memory boards to be a highly desirable option, (..)

      Hardly - the maximum amount of heat loss would be limited by the application.

      If you'd use this technology to build a SSD for a laptop or a portable media player, there are some hard upper limits on how much power (=heat) that SSD could draw. Things like battery life, the amount of heat a full system can deal with, acceptable noise levels for cooling fans, etc. If bandwidth = heat, the application would limit the maximum available bandwidth for a given power consumption.

      With that constraint as a given, I suspect that even a 100- or 1000-layer thick stack of memory cells would be capable of transferring the heat to its surroundings. Each memory cell wouldn't need a good 'heat connection' to the outside world - just a heat transfer to neighbouring cells good enough to prevent hot spots. Also memory cells could be arranged such, that areas that appear close from a logical (programmer's) point of view, are widely distributed from a physical point of view.

    Finally something that sounds like it's actually patentable.

    And not just patentable, but good solid research. It seems to me that lately, US companies have been cutting and cutting R&D budgets. The markets are so focused on who makes their current quarter earnings marks, and sinking money into innovation does not help towards making that profits goal. And because of this, it seems that we have lost touch with planning for the future.

    That always made me sick to my stomach. I am always thrilled when these big companies, that spun up and put technology where it is today, the HPs, the IBMs, the Xeroxs, the ATT/Bell/Lucents, etc., come out with something cool. I even like it when the small guys do something, but often they dont have the money to make it all the way to market.

    Anyway, my point is, I hope we see corporations (and everyone else, like NASA, etc) realize how important science and innovation are to our future. I hope that we can get back to the "old days" of (literally) shooting for the moon and achieving it, rather than spending money on fluffy marketing and trying to squeeze out margins with just barely passable work.
