    Check this out!! http://electic.com/webnews.shtml#981488047

    Go to the middle of the page. Look! Motorola is first to the MRAM landmark! This new memory is not only non-volitle, but offers insane memory densities (we're talking 10GB DIMMS for under $200) and is far faster than DDR, QDR, or Rambus ever will be! Will this new technology eliminate the memory bottleneck. No, the G5 is coming out remember. :D

    mmmmmmm......That would decrease computer prices and up the value.

    I just hope MRAM takes less time to catch on than DDR did. The graphics industry is sure to adopt it quickly though, as memory is a HUGE bottleneck as of late. :(

    Don't worry. Rambus will be there to sue the pants off of MRAM when it starts to have a presence. :rolleyes:

    ooh! Goody, Rambus. Let's pay 400 bucks for one DIMM of 128 megs :rolleyes:

    256 meg pc-100 sdram for G3 B+W : $149

    256 meg pc-800 rdram for whatever : $599

    I don't care if it's 700mhz faster!! I'm not paying 600 bucks for a stick of RAM!

    sorry to burst your bubble... Rambus has to be installed in pairs. So you would have to get two 128s or two 256s. Plus each chip requires a terminating chip. The terminators are $50 a pop. So to have a total of 256MBs you would use up 4 slots which is the max that most mobos have.

    Rambus ram also runs hot. It's the only memory that uses heat-sinks other than video card ram.

    This isn't really a competitor in the PC memory market.

    From the very next article:
    Rambus is too expensive right now, but it will come down eventually. With Apple's history of choosing the best (SCSI) over the most used (IDE,ATA,EIDE) I wouldn't be surprised if we see a Rambus Mac one day.

    Of course Apple has switched away from SCSI now, but if there remains a performance edge to Rambus who knows ...

    If Apple goes for the best than it would have to be DDR dude. Rambus chokes compared to DDR.

    What the hell are you talking about?! SRAM is only found in microprocessors. DRAM is what dominates the PC Memory market today. Did you confuse SRAM with SDRAM? SDRAM is simply high-speed DRAM synchronized to your CPU clock. I can't believe an Intel employee didn't know this! :p MRAM will eventually replace DRAM and Rambus, but will take a while to catch on. How much is Rambus paying you anyway to say these bogus things anyway? ;) Do you want me to also tell you why Rambus RAM can't compete with DDR despite having more bandwidth, or will you figure it out on your own? :(

    peak is not important... sustained IS.

    The best comparison I can give is the highway comparison. Rambus is a one lane highway with a speed limit of 600 miles per hour. DDR is a 6 lane highway with a speed limit of 150mph. DDR can handle a lot more consistantly that RAMBUS. DDR yields much better overall system performance because of this.

    Well said, although a bit exaggerated; DDR is less susceptible to memory stalls than Rambus. DDR also has a much lower CAS latency than Rambus RAM. Higher CAS latency means more time the CPU has to wait before receiving data from main memory. A low CAS latency is very important. 133MHz CAS2 SDRAM for example, outperforms 160MHz CAS3 SDRAM. DDR can keep pace with Rambus despite having less bandwidth, because it has low latency. :)

    yeah yeah, it WAS a little exaggerated. But I think I got my point accross.
