Rambus Wins Case Against Infineon

rednoise writes "Yahoo is running a story about how a Federal Circuit Court in California (I think) has (unbelievably) ruled that RAMBUS did NOT intentionally mislead members of JEDEC when the committee was developing the SDRAM specification. RAMBUS' stock skyrocketed something like 57% on the news. This is very bad news for owners of computers."

      You just add clauses to the contract which, in this case, demand that RAMBUS has to state truthfully that they don't own any patents to the technology shared with JEDEC, and a subclause, that if they do or claim in the future, the patent rights will be transferred to JEDEC in case RAMBUS wants to claim IP (using a patent they shouldn't rightfully have, according to the above hypothetical clauses...)

  3. RDRAM vs. DDR by netdemonboberb · · Score: 5, Interesting

    Why is RDRAM a bad thing for computer users? I think promoting better technology is a good thing for users. If people promoted the better technology instead of the cheaper one, companies couldn't dump their obsolete products on the market in order to decrease sales of the better technology. If people bought a product based on its quality, we would have things like organic LED displays instead of truly obsolete LCD screens and CRT monitors.

    I don't know where to stand on the issue of who had prior art, but I have talked to people on both sides and they seem to both have valid arguments. I don't believe any of the companies involved are boyscouts. What I am interseted in is which is the better technology. Obviously, if you look at the specs of Rambus, you will see that although DDR 266 is just a lower stepping of PC133 Ram and the bus is double-pumped. Rambus, on the other hand, has a lot more going for it. Its bus has less traces and allows you to more easily have more than one channel. It is also capable of shutting off portions of itself not in use.

    If you look at a Tom's Hardware article It mentions that there is a limitation with using parallel designs due to uncontrolled impedence.

    Not to mention that memory benchmarks available on many sites show that DDR can't continiously maintian its bandwidth like Rambus can. Instead, its bandwidth is spurty.

    Also, Rambus has many new things on the backburner.

    Rambus memory has also become much cheaper. I believe in leaving the decision of whether or not
    Rambus infringed on patents to the courts and going for what is the best technology so you can give it a boost. What holds back RDRAM in terms of price is that there isn't enough being sold.

      This was about Rambus' underhanded tactics with JEDEC which required all members to put patents related to what they were pushing as far as SDR and DDR SDRAM on the table BEFORE they made the specs final. Rambus, however, didn't do that. Instead, they held onto their patents while helping all the ram manufacturers settle on the SDRAM and DDR SDRAM specifications. Later, when the market wasn't adopting RDRAM fast enough--and the memory manufacturers saw no need to get RDRAM licenses (only samsung was making them at the time), Rambus went out and started telling the same ram manufacturers they worked with that they had to pay licensing fees.

      Technologically RDRAM's fine with some weaknesses early on as far as the desktop platform (embedded was another matter). Had Rambus acted honestly from the start, this whole matter could have been avoided.

      Theoretical performance doesn't hold up in practical applications. That is why there is SPEC. Besides, RDRAM is designed so that you can easily make it a multi-channel architecture:
      Quote: "By moving the core logic to the CPU and thus incorporating the Rambus Memory Controller as a part of the CPU itself, much of the current latency problems plaguing the technology will disappear. Both Sun's upcoming MAJC and the Playstation 2 are examples of embedded solutions with ondie RMCs. Another example is Compaq's upcoming EV7 (Alpha 21364), which also uses 8 channels to support massive bandwidth requirements and to keep latencies down (instead of accessing large volumes of DRDRAM in serial from a single channel, which would increase latencies)."

      DDR SDRAM is more complicated to design in a multi-channel layout because of timing and motherboard design complexity issues. Besides, DDR SDRAM can't sustain its peak bandwidth even close to as well as RDRAM. Bursting isn't sustained bandwidth.(Remember, to transfer a byte, you have to transfer a QWORD. To transfer the next byte, you have to wait an entire clock cycle). Therefore, it only really allows 1/4 the peak bandwidth in this case.


      A very old article from Ace's Hardware says: "The Rambus channel sends out the data twice as fast as the SDRAM, but the SDRAM can send out the first 8 byte without waiting, while Rambus has to transfer 16 bytes. As Rambus can send 2 bytes every cycle, it takes 4 cycles of 2.5 ns to transfer 16 bytes or 10 ns."

      Of course, this is regarding 800Mhz RDRAM, and 1066Mhz RDRAM is currently out.

      Also, not many applications only send 16 bytes at a time. For random access bursting applications, like servers, this is common. On the other hand, for 3d games, you want a sustained bandwidth to send all that data to the graphics card.

      The aforementioned site speaks of examples where DDR SDRAM would be better because of its lower latency. In those cases, though, RDRAM will still be adequate.

      Also, I'm curious to see any mentions of RDRAM versus DDR performance on newer chipsets.

      Since memory bandwidth depends on FSB, Intel systems should have an advantage.

      >The belief that RDRAM is a superior technology to >SDRAM is at best a matter of opinion and at worst >an absurd myth.

      Didn't see you try to refute the fact that unused cores shut down (great for power management).

      > RDRAM makes great sense when you're not using >very much of it (down in the ~16 MB range...

      Comparison: 1GB system.(Picking anything more would severely skew things in RDRAM's favor).

      PC3700 DDR vs PC1066 RDRAM
      source of prices: pricewatch.com

      Generally RDRAM comes with two channels, while DDR generally comes with one.

      PC1066 RDRAM theoretical peak bandwidth (2 channels)= 1066*2*2 = 4.3 GB/s

      DDR3700 DDR theoretical peak bandwidth (1 channel)= 466 * 8 = 2.98 GB/s

      Price:
      DDR (512MB modules * 2) = $145 * 2 = $290
      RIMM (256MB modules * 4) = $80 * 4 = $320

      Yes, the motherboards for RDRAM based sets are more expensive, but the memory appears to be bearly more expensive in this case for twice the theoretical bandwidth. The RDRAM 512MB is more expensive than DDR 512MB, but since you usually find RDRAM in higher-channel configurations, this isn't an issue. Comparing prices is difficult since you have to pair RDRAM up.

    and I'm sure it is, but has the past 5-8 years of massively faster development slowly sucked the joy out of computing. The mega-corporations and scumbags like Rambus who deal in little white lies and gray areas are making this a joyless industry and hobby.

    Maybe if we would have slowed the pace, not tried to jump start the PC industry with clock speed wars and bus bandwidth statistics, and as an industry concentrated on elegant solutions, innovative design and bringing something truly new to the consumer the market for PCs and software would not have stagnated so brutally? It's more than obvious that the current approach failed.

    The massive interest in the first wave of iMacs proves that consumers are hungry for something new, but marketing clockspeed and Apple's insane need to keep prices high killed that movement. Maybe a glimmer of hope from Small Form Factor or Mini-ITX (which I sit and type from at the moment)?

    What the hell does this have to do with Rambus? Rambus is part of the brute force/clockspeed eccentric computing industry. They have zero interest in the customer or industry partners, just in money (I know, I'm a capitalist pig at heart too, but there's more to it then that). When their product doesn't sell, they sue their partners, partners gained under false pretense.

    So would the industry be better off if we were just getting to 2gHz? If DDR was just taking off in the market place? If Microsoft concentrated on fixing Windows 95 instead of pushing out incremental upgrades every 18-24 months? Would processor upgrades feel really substantial if the architecture were more elegant and devs more concious of performance? If Linux devs stopped trying to emulate the Windows desktop and feature creep and tried to break away from the desktop metaphor? Would it be a better industry (and would the consumer still be interested) if Apple had 30% market share and users really had alternatives?

    Yes, the market would be more fragmented and support would be more challenging. Yes, 3gHz is cool, but who needs it? Yes, XP is better than 95, but could we have gotten there in 2 upgrades instead of 5, and caught the security holes along the way. How cool would the Linux desktop be if KDE was built from the ground up not to be like Windows (flame retardent boxers activate!)?

      I agree, and I think the issue that you're really hit upon is one of quality vs quantity. The computer industries have been pursuing the latter strategy for quite a long time. When apple started to design chips that had less clock speed, took less power, and had more "muscle per clock cycle," the marketing dodos at Intel said "it's slower because ours has a bigger number" and customers believed them. The same is happening with the big AMD vs Intel battle. AMD had to rename it's line to this ridiculous 2400+ kind of stuff.
      Apple gave up on the clock-speed game and finally focused instead upon making beautiful products that the Apple fanatics would buy. I've never been a fan of their gear until recently, when I messed around on a Powerbook. I felt right at home in that BSD environment. I actually think that the computer industry should moving more in this direction. More towards open source, more towards beautiful and powerful products and not just pimping out hardware.

I don't like the RDRAM design because serialization of RAM is a tradeoff on bandwidth; adding the necessary communications protocols will further restrict the flow of data. To offset the serial bottleneck, the clock speed must be greatly increased. This leads to greater heat dissipation, fewer units that pass QA, and ultimately, a less scalable solution overall.
