Nanodot Memory 100X Faster Than Today's Memory Chips

By - Source: UC Berkeley | B 39 comments

Researchers from Taiwan and the University of California, Berkeley, claim to have developed a new memory technology that can exceed the speed of today's mainstream charge-storage memory by up to 100X.

According to a paper published in the current issue of Applied Physics Letters, the device uses non-conducting material that integrates horizontally aligned, non-overlapping silicon nanodots (Si-QD), each of which has a diameter of about 3 nm and represents a single memory bit. The storage function is provided via a metallic layer on top of the nanodot surface that is employed as a metal gate to control the on and off stages of the nanodots.

The published paper claims that the operating voltage of the non-volatile memory device is 7 volts and the program/erase speed of the nanodots is less than 1 μs. The storage process itself uses brief bursts of green laser light to target specific regions of the metal gate layer and reach individual nanodots. The scientists also claim that the "materials and the processes used for the devices are compatible with current main-stream integrated circuit technologies" and "can also be applied to other advanced-structure devices."

There was no information on the capacity of the memory device and a possible production beyond a lab scenario.

    The thing is, these things don't matter much to consumers until REAL products arrive. Like the super dense batteries, super quick charge batteries, carbon heatsinks, etc., yeah they sound awesome but I'm waiting for actual market release.

    Its not just about the actual market release.
    I think the point here is that numerous technologies that are much more advanced have been developed throughout our industrialized history, but few have made it to full-scale production.
    It might be the case with this technology as well.

    Keep in mind that whenever similar things are published, they often get forgotten only to re-appear online years later, and disappear again.

    Its also not a question of mass production at lowered costs.
    We could have easily done all of that some time ago with numerous other technologies.
    But keep in mind that the market doesn't work by suddenly transitioning to technology that's for example 100x more powerful/efficient.
    Companies make more profits in the long run by making smaller revisions of existing technologies, slowly incorporating some minor features and overcharging the consumers simply because they can.

    Technology that is in use today is highly stagnant actually.
    Its quite sad really.

    100x faster @ 4kb capacity :(

    7V? How much power does this technology use? How much heat does it generate? At first glance, this may be fine for Big Iron, but I don't see it "Coming soon, to a laptop near you!"

    So... just under 14 years?

    the thing uses LASER so it's hard to replace NAND in some small size applications, like the HDD is too big to fit in your phone

    still looking forward for products using this technology

    ill be dead before any exciting tech comes out, sucks being 24 right now... ill die just as tech gets advacned enough for me to be interested in it again.

    green laser? hmm....HD manufacturers already has technology similar to this using very fast burst of laser to flip magnetic properties of the material.

    Think how I feel at 40............

    But yes I agree with you. There are too many people scared of new tech who are holding us back. Look at this website........ 1/2 the posts on here are people lamenting newer/better/faster.

    The good enough crowd....

    And this is a tech website. Imagine the mentality of the general public.

    bla bla bla bla. means nothing. where's a product? or even a working prototype?

    exactly. This is a good tech opportunity and we will see products as long as some hardware manufacturer jumps at this

    i want newer, but not in a poor direction
    i want faster, but not be required to get it
    i want better, but not better to some and not to others

    look at windows 7, yea, its better than xp in some cases, but others i would rather have xp still, i think it went in a poor direction

    i want faster processors, graphics cards and so forth, but i dont want games programed with tri sli in mind and hopeing future cards sort it all out, or slopilly coded programs that bloat so much they have more features than an older version, but preform worse

    and i dont windows 8 that will be great for tablets and phones be the corner stone of how a pc will be made

    ill probable get downvoted for not calling windows 7 my god and saying xp was better in many ways, or the audacity of me for not wanting quad sli required for even the start menu of a video game to go at more than 15fps... but thats how i feel.

    at the rate things are going, tech will just get good enough by around the time i hit 80, but if my grand parents are any indication, id rather be dead than get that old with my genetics.

    i want, smaller, faster, better. Price will go down eventually anyways so might as well put it out already. Start using fiber in MB as well, i dont know what the hold up is but i will be in line to buy one of those puppies if it ever comes out. It makes me sad that new nvidia cards were still using the 9800gt framework :(  We have innovation already as stated in this article (and many others) but there is no one willing to fork over the capital needed for practical application.

    Like when the first planes flew, it may or may not have been obvious it was going to become mainstream, but it gives us a glimpse into what can happen down the road.

    @Douglas

    if the new memory responds at 1us (1MHz) which is supposedly "100x faster than today's memory" then today's memory runs at 10kHz. are you sure you got the units and numbers right?

    I was hoping that I am still living to see this come to reality.

    ik242 - a microsecond and a Megahertz are not equal measurements... one is a measurement of cycles per second (hertz) and one is an actual measurement of time... where did you get 1μs = 1MHz?

    I'd like to complain here about technology or time or life or something, but it already been covered above. I think I'll just have my life. Anyone else?
