Carbon Nanotube Memory on the Way 134

Cyberherbalist writes "Nantero, a nanotechnology company, is expecting prototypes of products using NRAM technology (nanotube-based, non-volatile random access memory) to be available in 2006. In the article at nature.com, it says that 'the company has succeeded in making circular wafers, 13 centimetres in diameter, that hold 10 gigabits of data.' And they are ten times faster than 'flash' memory."

        Why would you do that?

        Current DRAM chips were there years ago: current DRAM chips are around 1Gbit per square centimeter. On a ~5" wafer, this means ~40 potentially working chips per wafer and 40Gbits/wafer, four times as much.

        And as far as downtime reduction goes, NRAM would be no good unless the server has time to suspend-to-RAM... so you would still need an UPS or ultra-capacitors to cover this.

          Well, unless the server was written using memory transactions [microsoft.com], which are starting to look like a good idea for other reasons also. If you had a transactional layer on top of your NVRAM, then you could structure things to allow crash recovery as well; then you could recover from any crash at any time.

          Yup, 32 wires horizontally and 32 vertically, plus usually 1 or 2 wires for reading the data back. Must have been a PITA to install in a machine. I've never actually seen core memory in person, but have seen a few pictures of it. A bit of a trivia tidbit: An Wang, of Wang wordprocessor fame, apparently invented the stuff (or at least was first to patent it). Man we've come a long way.

            ...when a byte is 8 bits. This is not always the case. Even modern parity memory stores 9 bits per byte (well, 36 bits per word), even if only 8 of those virtual bits are visible to the user.

            It doesn't seem completely impossible that a machine old enough to use core memory might have also had 4-bit bytes, giving 256 bytes per kilobit (yes, kilo and not kibi - you can't make me say it).

            • 4-bit bytes never happened...even counting 1 byte == 1 character (false!). IIRC, baudot used 5-bit characters, morse used variable bit characters, and Conteniental Code used ternary notation variable bit length characters.

              But nobody used 4-bit characters. (4 bits == 16 combinations. Won't work.)

              Besides, IBM *invented* the term byte for their 360 series computers (s.a. EBCDIC), and specified it as 8 bits.

      For one, it's first-gen stuff. It will likely gain density quickly in the future. Also, don't forget this is basically NVRAM: way faster than a hard-drive, and way more permanent than DRAM. It fills a unique niche and cannot directly be compared to or replace either of the two. (Well, it could replace hard drives, if it shrunk enough). The day is coming (slowly) when the primary storage on any computer system will probably be some sort of nonvolatile solid-state device. Hard drives with spindles will be for bulk data (music, movies, documents), while the OS goes on the nonvolatile ram which is neccesarily much smaller in size, but more reliable and faster to access. You can do things that way now under Windows or Linux by buying a 1-4 GB-ish solid state flash disk for your root disk (or C: drive) and then putting in a large normal hard drive for all your bulk data, but current SSD technology is overpriced and suffers from various little problems, both of which make it impractical for mass deployment even if the OS vendors put more thought into supporting the setup.

    Anyone remember 'holographic' storage that was going ti give TB's in something the size of a sugar cube, or all the other similar technologies touted over the last 10 years. They all came to nothing, we are still stuck with slow HDD's and flash technology. 10 years from now things will be much the same, we will have even bigger, marginally fast HDD's.
  • Ever heard of the FLASH hard drives? Well, think about it. 10 times faster than flash drives, no limit to the number of write operations... this has the potential to become the *ultimate* hard drive technology. Silent hard drives, which can be operated no matter the humidity conditions (7500+ RPM hard drives don't operate very well in places with high humidity and heat, i.e. coasts)...

    Only one thing concerns me, tho. 2 years ago, Nantero had announced the fabrication of their nanotube memory. I was skeptical then, and I'm still a bit skeptical. What if their prototypes don't work? Will Nantero suffer the fate of so many dot-com's we all (don't) know about?

    Only time will tell.

      I am an old timer, been through the tube age, then on to transistors with tubes, then transistors then the first chips and on and on... All new technologies have a rough start, I know we will soon have solid state memory that is cheap, reliable and non-volatilse that will allow our computers to be instant on instead of loading all of the crap we now have to. Do prototypes work to begin with, hell no, but give it all a chance. A techno nerd before they were words... Rod
      • I agree with your perspective. The only really big hiccups I recall where prototypes were talked about in the popular press as the next big thing were "silicon was too slow and was going to be replaced by GaAs by the mid 80's" and "Bubble Memory".

        Some things also take longer than expected to become economical. I saw Vertical Density recording in floppy diskettes at a Hitachi exhibition in Tokyo in 1983. IIRC, they had >3MB in 3.5in and >8MB in 5.25in. I can't remmeber if there were hard drives there

      • There have been and still are a lot of "instant on" computers. The problem is that people expect more of their computers at an economical cost, as such, the idea of instant on gets thrown out, though, IMO, sleep and standby gets most of the functionality right there, you get a computer that's on and functional in a couple seconds and the computer takes very little power in standby/sleep.

      Here's a link to news from year 2003 where they accounced it:

  • Ok, holy freakin crap, but this thing is HUGE... This is bigger than most hard drives , and it holds ONE gigaBYTE of data . You are NOT fooling me with your non-standard measurements. I would have expected a bit better from "NANO" technology.

    This is not going to replace ANYTHING with these dimensions... I can get an Ipod NANO with 4 GB of space, and I get a screen, a click wheel, audio processor, and a battery in less space...

    When I started my study in 1989 the Bucky ball had just been discovered. Carbon nanotubes followed a few months or so later. And now, 15 years later we see the first products based on them appear. It's nive to have seen something develop from first discovery to useful product.

  • I wonder if this type of thing would allow a DSLR to be hacked to shoot at 24fps continuously. Just a thought.
  • Uhm, yeah. I thought nano technology was supposed to be small ;P

    10 gigabits in a 13cm diameter wafer? Does this really sound that good to anyone? I mean a little flash card is like 3cm wide and holds a gigaBYTE. This wafer holds 10gigabits/8bits = ~1.2 gigabytes. Harddrives? Assuming you have a bunch of these wafers for "platters" the size would still be pretty limited.

    So finally when the system crashes we can say it went down the tubes and really mean it!
  • Several times every year, we hear of some company expecting to soon release a storage product that'll be orders of magnitude better than any existing technology, yet somehow they hardly do.
  • As a nanotube researcher, I usually have some snotty remark about how no one pays attention to reality when it comes to carbon nanotube research. However, this thing works. It's really not that complicated, and has passed scientific review multiple times. These people have been in the nanotube research community almost as long as it has existed. They are real scientists, doing real work.

    I'm not saying they're going to hit the exact specs they're shooting for, just that the basic science is prooven, and
  • I want to know what happened MRAM, a magnetic based, faster, and static replacement for our current DRAM? Guess they are faster at producing acronyms then product.
  • I am in charge of the SEM on our campus, and we have people from physics over all the time, and last month we had a guy over who was making carbon nanotubes.

    The ones I saw were made from Acetylene gas and ammonia. A tiny particle of Iron starts the process of tube formation. The carbon adheres to the base of the iron particle and builds up from there, the iron particle determining the diameter of the tube.

    Reminded me of the smelly back snake fireworks I used to like as a kid.
    Except that they are a lot small
