    The transistor itself contains several atoms, although it's still MUCH smaller than today's devices. A one-electron difference in charge on the transistor's gate is all that's needed to switch it on/off.

    Okay, it's been quite a long time since I took high school chemistry, so maybe something radical changed in the field since then. But I distinctly recall only about 200 to 250 possible elements. Which isotype of which element does this single atom belong to?

    Oh hell! This can't possibly be right. Not even Japan can alter the laws of physics. Let me read the article to see what the truth of the matter is... ...yes, Slashdot goofed again (does this surprise anyone). They read the eeTimes' equally innacurate headline and never bothered to read the article. Quoting the real information, we find that:

    The transistor Aono is developing makes a switch circuit consisting of ... a 10-atom-diameter cluster of 500 silver atoms that acts as a capacitor...

    and

    "We can make an atomic switch in a cluster of silver atoms"

    Very amazing. But it's not a "Single-Atom Transistor" like Slashdot says. The key component in the transistor may be a single atom, but the transistor itself is not.

  • And when people realize that perhaps faster RAM instead of higher clock speed makes MS word run faster, you think that they will turn down the opportunity for more speed?
  • we need to take the emphasis off of multi-gigahertz processing, and take a step back to develop other components to the same technological advancement

    As others have pointed out, this is basic research which can be applied to all kinds of circuitry, not just CPUs.

    However, even applied to CPU development, decreasing feature size means more than just faster processors. It also means that you can create a processor of similar speed to what we have today, but with lower power consumption and better chip yields.

  • But they *are* working on all that good luvin'. To increase parallelism, the folks working on Alpha and Intel's Foster are doing SMT. Intel's working on Infiniband to increase bus speeds, while AMD's got LDT which will either replace or aid the Infiniband thing (depending on who you ask). DDR's basically here, and with luck we'll see a QDR standard soon (Quad Data Rate - like Double, but Quad ).

    The thing is, each of the groups needs to keep on working, and getting a single-atom transistor in the lab is a far cry from getting one in your grandma's new computer from CompUSA. You've gotta lay the research groundwork, then maybe get some standards, and only then start worrying about actually producing something to sell. All of the things in the first paragraph are pretty much pie-in-the-sky at this point, but so are single atom transistors.

  • Just for the record. This isn't anything new. The Bus speed has been the bottle neck since the 486 days although not to the same degree as it is currently. Lets also not forget that bigger faster better isn't always the case. A bus that has twice the data bandwidth is faster than a bus that has half the bandwidth at twice the speed. Nobody looks at a Sun as being a slow machine even though by current pc standards they are low on the core speed scale. The average Sparc clocks in about 500 MHZ. But they are running a 64 bit architechture and 64 bit bus so they don't have to have the GHz at the core. I know that I am WAY over simplifying things here but the point is, the bus being the bottleneck is nothing new. I think the big chip manufacturers are worried that by releasing a new chipset that is incompatible with older hardware(at least on an I/O standpoint) that consumers won't fork over the bucks for it. Look at RDram...people bought it. If you build it consumers will buy it. Esp. us dumb americans*smirk*
  • poke him in the eye. That'll impress him.
  • Some of the newer Athlon processors have 12x multipliers. That means the processor is working 12 times as fast as the rest of the system

    Not quite, because Athlon bus is dual-pumped, it moves data twice for every clock cycle, which means that for a 1200 Mhz CPU with 12x multiplier you have a 200 Mhz equivalent bus - the CPU is really only 6 times faster than the bus.

    As for the Pentium 4 and its 100 Mhzquad-pumped bus, it is 1500/(100x4) = 3,75 multiplier, which is even lower (and explain why this CPU is a screamer when it comes to bandwidth apps :)

    Although I agree with you that other components need more improvement than the CPU, I still wish my box could uncompress 50 JPEG at 2048x536 res. in less than a second (speed required to browse my picture library with ACDSee :)
  • Well, it's pretty hard to get below one atom, but I'm sure there's a clever and brilliant scientist out there somewhere who will figure out an ingenious way to up the ante even more. Stay tuned for further details on the next greatest invention on monday.

    Perhaps next we'll enjoy the single-quark transistor.

  • If you read the article, its a group of atoms arranged so that 1 electron makes the difference between open and closed.

    Its not a single atom transistor, its a transistor switched on or off by a single electron.

    All your base/collector/emitter belongs to us.
  • The trouble with making things so small is sooner or later one of those nano-scale components is going to be zapped by either a cosmic ray or background radiation from some other source. Considering how many of these particles hit our bodies each second, this could be a serious problem. Its not a big deal for current technologies, but when you are talking about single atoms and single electrons....

    So, you are going to need very clever circuits to detect errors and switch-in replacements, which makes the thing bigger.

    Speaking of Moore's Law, does this mean that in 18 months we'll have scientists promising half-atom transistors?

    Naah, they start with Lawrencium 262, then in a few months they kick out a few neutrons and protons to make Fermium 256 (just to make these calculations easier). Then, with 18 month steps: Xenon 128, Zirconium 64, Sulphur 32, Oxygen 16, Beryllium 8 (9 is more stable though), Helium 4, Hydrogen 2, and finally Hydrogen 1 (ehm...a single proton).

    While the single-atom transistor thing is cool, it seems to me that the interesting part of this discovery/invention is the super-tiny wires they have to connect them. Now THAT's cool, and a big problem down there at the nano(pico?)-scale level.

    What I want to know is, how will they connect this with normal electronics? They'd probably need 5 or 6 buffers in between to step down the current so as not to fry the tiny wires. Also, wouldn't a chip made with this technology be super-sensitive to interference? If a random cosmic ray hit it, it would probably be fried.

    Hope they can solve all the problems. This sounds like really cool technology.

    In IEEE there was an article a year ago on single atom AND and OR gates. Basically they were dealing with the spin of the electrons. This would be equivelant to two transistors(maybe). At the time I am not sure if it was theoretical or not, but it does not suprise me. The problem is dealing with an interface to that level of technology. How do you connect a wire to this to actually get the output somewhere. This is the problem they had a year ago. If you have a micro chip that has atom sized transistors, how do you connect the wires to these chips to get the power to. Also with a conventional power supply how do you step down the power to that level without the massive overhead of creating a major conversion mechanism. 220/110 W to ??

    Anyway it is a step, now we need the leap. What would really be neat is to see smaller PC parts today. A 2" network card and a 2" modem connecting to an 8"x6" MB would be sweet. Then my pc would be cut down to about 1/3 its current size. A cdrom drive that only 1/2 the cd went it rather than a drawer. Hmmm

    Better fab processes improve all the microcircuitry, not just the main processor.

    Incidentally, the old modular tech you can snap together with thick, clumsy fingers can't be improved much further, which is why it's lagging. There's no sense bitching about your cheap swappable DIMMs when you won't shell out for faster RAM or buy a non-expandable machine. There is faster RAM available, it's just more expensive and needs a special set-up. Same thing for hard drives; people buy gigs, not MB/s.

  • read the article, people! It is not a "one atom" transister, it is a 500 atom capaciter and 3 3-nanometer wires and the gate 4 nm from the capaciter. It only uses one electron for the current, which is why it is listed as 1 atom. There is still pleanty of room to shrink the transister.

  • By the laws of quantum computing, that is NOT outside the realm of science, though, I think we're more likely to hear "single polymer beowulf cluster" than "single atom beowulf cluster," since, without more than one atom, you don't have a cluster yet.
    Whoever marked you a troll should be dragged out to MIT and forced to sit in on a semester of Quantum Theory: Engineering for the Future

    No, I don't know who comes up with these 1940's titles, but I'm willing bet it's been the same guy coming up with this stuff for the past 60 years. He's probably eight or ninety and a millionare with his own naming firm that now caetors to those disk-hogging power-point presentations.
  • The happy little lepton we like to call the electron cannot be used as a transistor because it cannot be kept still. If you could stop a lepton, it would "shatter" into another form of radiation--in theory, that would be mostly microwave radiation though, it could invert or, after the moment of microwave release, revert, into beta radiation.
    Though, I'm sure you only meant that as a joke, I just thought I'd throw in some momentary thought. I'm having a good day for a troll.
  • First off, in case you didn't actually READ this article*, the refence is to the thickness not the length of the transistor. Second, due to the ever annoying presence of Ohm's law, what starts off as a single electron could just be capacitated as another form of energy until it is release by the atom that transfered its energy, most likely in the form of heat.
    This is why the field of superconductors is so much more interesting--perhaps, one day, it will only require a single electron, but you'll still be measuring atomic thickness.

    *New abbreviation for /. : RTFA; I'm sure you can guess what it means.
  • As I mentioned before, due to Ohm's law, unless this is a superconductor, it takes more than one electron, and the "single atom" is about width of the relay switch, not the total number of atoms involved in the transistor.
    Normally, the atom chain would be guessed at Si, silicon, but it sounds like it will be Ag, silver.
    200-250 is not a bad guess...for the number of pokemon. 124 would be more accurate by ways of the atomic table, including the undeclareds, the unnamed and the unstable.
    Now that we've had a jausle into the world of chemistry, can we play a game of chartuse camerrida?
  • ersonally, I think I'll live to see Moore's Law get sent to /dev/null with things like "Man will not fly" and "Man will never walk on the moon"*.

    With the extensive probing into quantum machinery**, the question is, "How soon will it be that processors create their own dimension to perform advanced mathematical calculations. The question is, "When will be using planck's width to record data rather than Fe-Si combinates?" The question is, "Will the term 'wireless' come to mean that a small quantum bridge is created by the computer to read the data on another computer atoms?"

    I feel that too much emphasis is being placed on processor speed today. An important processor is nice, but we need to take the emphasis off of multi-gigahertz processing, and take a step back to develop other components to the same technological advancement. We're rapidly approching a point where a two, five, or even ten gigahertz processor isn't going to improve performance, because it's no longer the limiting factor. I'd love to have my own processor made from single atom transistors, but first, we need to work on improving bus speeds, memory latency, and hard disk access time. Without all of these factors working in unison at high speeds, the only thing you're going to get from an ultrafast processor is a lighter wallet.

    Just look at some of the benchmarks on Tom'sHardware [tomshardware.com]. The majority of them are all dead even after processor speeds hit 8 or 9 hundred Mhz.

    Some of the newer Athlon processors have 12x multipliers. That means the processor is working 12 times as fast as the rest of the system. This is wasteful, and you end up with a lot of dead processor cycles because the RAM/system bus can't provide enough data for processing. Manufacturer's need to stop throwing money at superfast processor development, and work on improving system bus speeds, and latency/throughput of RAM.

  • And the half-life of Transistorium is eighteen parsecs?
  • The end of Moore's Law my ass! Bring on the single-electron transistor! THEN we'll be getting somewhere (quarks notwithstanding).

  • Terra-Transistor Processors + Terra-Terra-byte Storage + IBM's Quantum Teleportation [ibm.com] = "Beam Me Up Scotty"
