    -How about speed? Is this fast RAM or does density increase latency?
    -If it fits into the size of a human hair, could this technology be used to develop really tiny monitoring devices or other PC hardware?

    This is alarming! If they continue making progress at current late, it will take only aproximately 42 years until they have created a memory chip so dense, that no bytes can escape, infact the chip sinks through the fabric of space-time. Any data within 42 square kilometers will be suck in through the event horizon. The only escape from being drawn inside is growing a big head, since the Schwarzschild radius is aproximately 30 cm.

  • HP Labs Creates Densest Memory Chips To Date

    By Matthew Fordahl, AP
    San Jose, Calif.
    6:29 PM EST Mon., Sept. 09, 2002
    Using molecules as building blocks, Hewlett-Packard researchers have created memory circuits 10 times more dense than today's silicon
    chips under a process that could be faster and cheaper than current technology.

    The advance announced Monday could lead to more memory within a smaller space than what is now possible.

    "We believe molecular electronics will push advances in future computer technology far beyond the limits of silicon," said R. Stanley
    Williams, director of Quantum Science Research at HP Labs.

    The high-tech industry's growth has been driven by packing more transistors -- or switches -- into smaller slivers of silicon. Within
    the next decade, however, current technology is expected to reach physical limits.

    Researchers are looking for approaches that could continue the pace of innovation, yet without abandoning completely the industry's
    silicon foundation.

    Williams, who presented his findings at a symposium for the 175th anniversary of the Royal Institute of Technology in Sweden, said
    the high-density memory his team created fits inside a square micron. That's so small that 1,000 of the circuits could fit on the end of
    a strand of human hair.

    The memory is rewritable -- held on an organic synthetic molecule -- and can preserve information even after voltage is cut. It behaves
    much like today's flash memory, commonly used in digital cameras, music players and cell phones to store information even after a
    device has been turned off.

    The difference is that the new memory could be much cheaper to make.

    Conventional semiconductor products are created by etching transistors into silicon by shining light onto light-sensitive chemicals.
    Williams' approach is more akin to contact printing used in creating vinyl records -- but at a very small scale.

    The masters were created in about a day. They were then pressed into a polymer layer on a silicon wafer, and then into a single layer
    of electronically switchable molecules on top of the silicon. Such molecules switch on and off just like a standard transistor.

    "It took just a few minutes to make an imprint," Williams said.

    Still, the technology is at least five years from being commercially available, Williams said.

    "Things are moving along faster than we anticipated," he said. "Even given that, we're just now demonstrating feasibility, and it's a
    long way from feasibility to product."

    The demonstration memory holds about 64 bits of data, thousands of times smaller than the 128 megabytes in the much larger chips
    found in today's personal computers.

    And the success rate for the manufacturing process was only about 20 percent. The biggest challenge was sticking -- something anyone
    who has fried an egg can understand.

    "When we peeled the mold off, we had a material, or parts of the circuit, just literally pull away," he said. "That's a problem we have
    to address and improve in our processing."

    Williams' group also built a simple logic circuit that can address specific areas of nanoscale memory.

    "It's a necessary step in order to have a real memory made out of this technology," he said.

    The work is "a very important step forward in a years-long effort," said James C. Ellenbogen, principal scientist in the Nanosystems
    Group at the MITRE Corp., a not-for-profit research company.

    "This is certainly a really impressive step forward for them and the whole research program as well as for the entire electronics
    industry worldwide."

  • So does this mean i can get soon 10gb ram's and put there that stinking wind0ze to perhaps to prevent it from being so damn lagged even with newest hardware available?

    Tho, even i'd had that amount of ram it would be one pain the ass trick to get wind0ze into ram and boot it from there... so anyone done that? ;)

    time is 12:48AM here, perhaps it's time to get my breakfast... and change coffee to juice =)
    • YES, this is *EXACTLY* what it means. With the fact that this memory is faster than hard drives and unlike your RAM keeps its memory when voltage is removed.

      I can see putting 5 or 10G in a box for the OS and applications. Hard drives will be for your content perhaps.

      Perhaps Windows will still be around by the time this makes it to market. So what? Windows itself may be fast, and may be be _more_ stable by that time. Now take that same system put a Unix on it and compare. Same old game, just faster and better.

    ...and this little factoid,

    But seriously, now, isn't this aricle a bit to dumb-downed and fluffed up for Slashdot?
    Oh...wait. We don't read the articles anymore.
  • As much as IBM researchers, etc.. would like to believe that silicon will die and be replaced in the near future I doubt it will happen soon. Producing memory with size on the order of a micron is virtually useless. At the moment the limiting factor in the fabrication of integrated circuits are interconnections. Yes! The little pieces of metal that transfer signals around the IC. Currently 90% of delay in an IC is no longer due to the transistor but instead is cause by propagation delay through the transmission line. As it is not possible to fabricate transmission lines that can actually connect to memory as small as is discussed here, I can not see how this memory can be utilized. Does anyone know of interconnect solutions that could be used?
    • One advantage to sub-micron device structures (here, what, 125 nm2 devices, right, given 64 bits per square micron) is they are as near-field as you could want. Still, it is hard to see how you can get better stipline performance without going to superconducting materials. That is a long dicussion, better served by someone who knows more about it.

      What's the net result? Probably superconducting interconnects will be necessary to take advantage of this type of memory. Conductors with highly desirable LC characteristics (read nanotubes) may be another way to accomplish this without going to low temperature.

      Alternatively, asyncronous memory access / processing may be useful, though I know nothing about those ideas.

    Let's see... what are the implications?...

    In unrelated news, Rambus' lawyers have filed a series of initial patents, intending to amend them later as more details become available. Ivanna Bendemover, Rambus' CEO reassured everyone at the standards group that this has nothing to do with the new technology, stating, "You can trust Rambus to only have the industry's very best interests at heart."

    Back in the good old U.S.S.R., workers in the factories were encouraged to make heavy/dense electrical engines. The workers simply began adding weights to the motors, not actually increasing their horsepower or anything, and as a result, the U.S.S.R. made some of the heaviest engines in the world. Now, I doubt that's what's happening here (and the use of "dense" may not have anything to do with these types of chips), but I figured you'd appreciate the little story I had, courtesy of my Economics book.

  • "That's so small that 1,000 of the circuits could fit on the end of a strand of human hair."

    I can never understand why the mainstream media is so fixated with meaningless comparisons when covering science and technology. Is human hair some sort of benchmark in the memory industry? Do we care how many of these would fit on the end of a human hair? It seems like anything tiny is always compared to human hair ("fifty billion nanomachines could fit on the end of a human hair") and the benchmark for big things is the football field ("the solar wing is equal to the length of 200 football fields!"). Can't we dream up something more original?

  • With the amount of memory something like that could produce, I could finally ramdisk my pr0n collection.

    I'm sick of waiting for those images to load.

  • There are two cool things here. One is the use of a molding technology to replace photolithography. AFAIK this technique was pioneered by George Whitesides [harvard.edu].

    The second is the memory element, described only as "an organic synthetic molecule" acting as a non-volatile memory. Non-volatile is good; that means instant-on laptops. As for what it is, they don't say, but their recent work has involved rotaxane and catenane (see Figure 2 [aeiveos.com]). Bit flips in those molecules are reversible, another good thing, since you don't want memory that gets tired over time.

    This is all cool fun stuff, and I'm glad for it, but I had really been hoping for a follow-up of HP and UCLA's brilliant work on molecular combinatorial logic [google.com] in January. If they could add an active gain stage to that stuff, they'd really have something amazing.

  • This to match HP's densest management decision [slashdot.org] to date.
  • In the future children get constant free memory upgrades, wig sales will increase dramaticlly, and the only people who are bald will be the "computing impaired"
  • That seems to be the theme song of semiconductor fabrication by printing. We've been hearing about solar cells fabricated by printing for decades, display devices fabricated by printing for years, and now this. So far, nothing seems to have shipped.

    Most previous enthusiasm for this idea was for applications where you want lots of area but modest density, like displays. It's impressive that HP made it work at micron scale. But it's not clear that it's useful.

    It's more interesting that they made a smaller RAM cell. The mask and fab people were ahead of the device people early this year; they could fab a transistor too small to work. (That means the device physics people have to go to work on the problem.) This new gate may be interesting, with or without the "printing" approach.

  • Here's a scenario... in the future memory is virtually infinite. Gigs upon gigs for next to no cost in money & space. What will the government use all this storage for? Keeping archives of all your communications for "law enforcement" possibilities.
    Currently the only real thing stopping the governments keeping records of every single one of your emails and phone calls is the fact that storing them is physically impossible. This sort of development scares me as it's just one step further towards a surveillance society.
  • Okay, this is a great accomplishment. I am studying at KTH (Sweden's Royal Institute of Technology) where the symposium took place -- actually, I talked to a guy yesterday right after he came out of it.

    Anyway, it's cool but I just want to run some numbers before we get too impressed. They say it'll be 5 years before this is practical, and it's a tenfold gain in density. Now, what's the expected gain in density over the same period in a Moore's Law-type expectation?

    My trusty desktop calculator (a.k.a. Python) tells me that 2^(5/1.5) is 10.0793683992. Pretty damn close. So yay, we're still on track.

    I wish the article gave more details, though. The guy I talked to had a much better description of how this thing works.
