          The manufacturers of the actual silicon will always use *bit for the size because they are developing something independant of architecture, and therefore *bit is the most relevant notation of size. On a PC it might be relevant to use 'quads' as a measurement, as all machine code and addressing is done in 32 bits, whereas on some older microcontrollers the addressing is in 4 bits, so that would be nibbles. Perhaps some technologies want single-bit accessability, as the storage is not used to store addresses/instructions/ASCII. Using *bit is the only truly platform independant measurement, because the 8-bit bytes is aribtary whilst the bit is indivisible.

              A single chip stores single Bytes. A DIM or SIM is a smal plate with 8 or more chips.

              On a chip you can address every bit individually, or chunks of 4 or 8 bits, depending on your fetch and cash strategy.

              However on a DIM/SIM you fetch from all chips one bit each, and those get combined to a byte, or a word or a long word, depending on your architechture and the architectue of the chip/DIM.

              The logic on the DIM/SIM is responsible for combining bits from different chips to the words, the processor wants.

              Depending on usage of he chip, I mean planned usage, the ship might be organized in arbitrary word sizes. A common word size on a chip can e.g. be 128 bit for video ram.

              All the above is "principle" only. Today I guess it is far more complicated.

          Actually, there are plenty of reasons to measure bandwidth in bits not bytes.

          When I size/plan/order circuits, I need to know raw throughput in bits/sec, because I may be ordering that circuit for a dedicated purpose, which can have significantly different overhead and efficiency than a different purpose.

          Whenever you see bandwidth measured in Bps (bytes per second) you are seeing, at best, an estimate. The reason is that people are concerned about *payload* when you mention bytes, not raw throughput.

          As overheard increases or decreases per packet (which can be caused by fragmentation, poor application design, etc), then the amount of payload data per packet changes, while the raw throughput does not. Try this as an exercise. Open up an FTP sire via MSIE, and transfer a large file from a decent server near you. Note how long it takes, and the data rate MSIE tells you that it comes in at. Now, open up an MS command prompt, and ftp to that same site, get the same file, and note how long it takes, and the data rate it tells you.

          Same site, same link, same file, same OS...two completely different download times/rates.

          When I order any circuit...I want to know what the actual bit rate of the line is. I don't want some marketing mumbo-jumbo about 'bytes per second'...I may not even use an 8 bit byte, or, they may use a different interpretation of 'kilo' and 'mega' when quoting data rates. Bit-rate is pure...because a bit is a bit is a bit, and a second is a second is a second.

        First off, storage chip capacity is always measured in bits, and these chips are most likely (no, I haven't read the FA) 8Gib (eight gibibit, or 8x2^30 bits, i.e. 2^30 bytes or 1GiB). Look at your memory sticks and you will notice that they are equipped with mutliple memory chips, and the same goes for large capacity flash cards. This is not a 1GiB storage card, but a component that can be used to build large storage cards.

        What is new and interesting (for chip process nerds) about this is the 60nm process. Current chips are generally produced in a 130nm process. There are also 90nm chips in general production, and they're pretty much the shitnitz at the moment.

      They are using conventional storage standards. Memory chips have been measured in (multiples of) bits for decades. When I started paying attention, around 1980 or so, the state of the art was something like 4k or 16k bits for DRAM and those chips were 1-bit wide. Even 8-bit wide chips were, and still are, quoted with storage capacity in bits. Again from the early days, an EEPROM with 2048 words of 8-bits each was described as a 16k device.

      Further down in the article it is stated that "The flash chip is designed to let consumer electronics designers put up to 16 gigabytes of data on a single memory card". Note that they use the conventional units, bytes, for memory cards.

      Remember, different conventions in different fields. You may think its silly, but that's life and you'd better get used to it.

      And, since you ask: no, bits doesn't necessarily imply a rate connectivity. Raw connections are usually rated in bits per second but high level data streams, such as ftp download speeds, are often quoted in bytes per second. I do not know whether there is a parallel here between comms and storage in the different conventions used to specify what the raw technology gives you and what is built out of that technology. I would be interested to learn whether it is more than coincidence.

      RAM modules are usually "measured" in bytes. However, RAM chips are, and have always been, measured in bits. Mainly because it used to be common configuration in RAM modules to have 8 chips, and the module's total capacity in bytes would be the same as the chip's capacity in bits.

      RAM chips used to be referenced as something like "1x8x1M", which would be eight memory chips, each with one megabit, and accessing one bit of data at once.

    Can someone explain why the FLASH memory is sooooo much larger than the DRAM chip? DRAM is just one cap and one transistor per bit, while the flash uses a MUCH more complicated structure for each bit. It involves at least two transistors per bit, one with a floating gate.

    For the same size die, I would expect that the DRAM would hold a little more than the FLASH. Either the FLASH die is huge compared to the DRAM die in this case, or I am missing something.

    Can anybody clue me in?
    • OK. I just RTFA. The FLASH uses a slightly smaller geometry. But I am still surprised by the large (fourfold) increase in the FLASH size comapred to the DRAM.

        Possibly they can get away with larger die sizes on FLASH because they can get away with errors. Many blocks (up to 1% I think) of a FLASH die are allowed to be bad (but reallocated) at production time, whereas a single bad bit in SDRAM means that die goes in the bin. I guess that makes it possible to have good yields even with large die areas.

    • Take a look at a DIMM... it usually has a bunch of chips on it. The 2GB DRAM will probably be on a DIMM of 8 DRAM chips... making the DIMM a 16GB DIMM.

      I'm assuming that the flash chips are much bigger (in physical size) because they are meant to be used alone (and will cost a lot more), but the DRAM chips are meant to be used in groups in a larger package.

      Then again, I might not know what the hell I'm talking about.
    • True, a RAM cell is just one capacitor and one transistor per bit. However, the capacitor needs a much larger area than the other components. Its capacitance must be much larger than any stray capacitances in the circuit, to hold the charge that represents the bit without any errors for the length of one refresh cycle.

      The type of NAND Flash currently in use require just a single transistor to store two bits, either by the mirror-bit technology or by multilevel flash. A single NAND flash cell is 4F (F=smallest featuresize of the technology node). So it takes 2F to store one bit. Current DRAM cell sizes are 8F (or 6F with additional area sacrifice). Therefore the flash memory density is at least four times as high.

      In addition to that flash is MUCH easier to produce than dram.

    ....in a more/bigger/faster and more throw away culture. I'm impressed! But it's also depressing! How is that? Well, tell ya, this is like the horsepower wars out of Detroit in the 60's, more cubes and higher revs with higher compression. Ok as far as it went, but........it meant throw away cars, too.

    Tell ya whut I would be more impressed with technologically, if some RAM company wants to make a splash and show off some real branez. A smart and adaptive memory chip reader that you could stick in a ram slot like a daughtercard that you could then insert any mix or match multiple RAM sticks into and it would read and access and use them all.

    We are awash in so called "obsolete" RAM that is still functional. It used to be just a coupla decades ago we threw away stuff when it was broken. Now we throw away perfectly fine stuff, things that aren't broken, they are just "obsolete" although they might only be a few years old.

    Anyone see anything potentially wrong there? Same thing with CPUs. We have SMP mobos (and kernels), how about NON-SMP MO mobos, any braniacs got any examples of that, were you can mix and match older processors and keep using them? I know you can make a cluster whatsis with older boxes, I am talking a single machine that you could add tons of older oddball ram sticks to and plug in a variety of CPUs.

    To me, RAM and CPUs should be treated like drives and other peripherals, you should be able to daisy chain them better (different kinds, sizes, functions, etc) on a single machine.

    • You don't hang around with many marketing folks, do you? ;-)

    • ".......it meant throw away cars, too."

      what? many of those cars were easy to maintain and keep going. It's now that we are approaching throwaway cars.
      There dificult to maintain and cheap.
      Something become throwaway when it it cheaper to replace then fix. I can buy a new car for 7 grand. granted it's the bottom of the line, but I could buy one every 5 years and always be under warrenty.

      yes, that would be cool, but after a
    • Uhm, just because they're on the same MOBO, doesn't mean you DON'T have a cluster. Me thinks you need a good education in Parallel processing. [amazon.com]

      And for that matter, computer hardware design. [amazon.com]

      Its great that you are jazzed about salvaging older parts; harness this energy to learning about computer design.

      P.S.- I threw out my maxxed out PowerMac 7200 dual booting to linux/Mac OS 8. Why? Too slow. I had other machines to work on at home. Love's labour's lost.

    Last I checked, most memory technologies required at least 1-T per bit. I don't know if that's true for flash technology, but still. 8Gb would be 8+ billion transistors not including decode logic and amplifiers. Wouldn't this make these flash chips have the highest transistor counts on the planet?

    Last I checked, the highest transistor counts we had were around 400-500 million. That's like 1/16 of what would be needed to do this. What am I missing?

      Its currently at two bits per transistor. Search for "multi level flash", "mirror bit flash", "NROM"..

You never know when some obscure technology will suddenly become crystal clear by means of a helpful, knowledgeable story poster. My spelling has improved because of Slashdot, too. Thanks, guys!

  • I got one of those 1GB SD chips for $110 a couple of weeks ago, and now they're $94. That's a 10% drop in 10 days, and they're still dropping. And there's now a miniSD form, so 1GB the size of my fingernail, or 10GB the size of a stamp, is looking good. Samsung is driving down these prices. I'd love someone to get the power requirements down to the point where something like RFID could let me read them wherever they were stored in my apartment. I'd keep the data encrypted, and sticking them into every produ
