Hi Jdaasoc; Re: "I still don't like the idea of negative timing margins fixed by adding wait states in response to PCB trace issues." There are no "PCB trace" issues with DDR, any more than their are identical (but worse) issues with PCB traces in RDRAM. Since the measured latency of DDR is considerably below that of RDRAM, you should give up worrying about wait states as well. In addition, you should also note that the Micron article deals with an alternative technique for using DDR, not the one that is used in DDR chipsets, for instance, the AMD761 DDR chipset. DDR is used by all kinds of people for all kinds of things. It is the dominant memory for design engineers at this time, and all the Micron app note does is give an alternative way of using it. That is not how DDR is used in the chipsets you're dreaming aren't functional. Re: "Ian thinks DDR is not stable enough for business computers." That's total, unadulterated, garbage. If 266MHz DDR wasn't workable with business, then why are so many companies intent on using it exactly for that? Sure Intel said it wouldn't work, but Intel has said stuff like that (when they didn't have the product available yet) for years. As of right now, 266MHz DDR has taken over most of the high end AMD chipset use. With Intel, the transition is slower because neither DDR nor RDRAM provide much benefit to the 1GB/sec limited PIII FSB. When chipsets that support DDR with the P4 become available, you will see massive use of DDR in all kinds of systems, just like the exec at Iwill told you, you loser. (#reply-15892716) I'm not going to waste my time (hopelessly) trying to explain esoterica like "clock domain transfer" circuitry to you, suffice it to note that if I explained how that works, you likely wouldn't believe it would work either. If you can't understand a simple 2-page design note, why are you using your judgement to invest in a high tech company that just got convicted of fraud? -- Carl Go buy some RMBS leaps for your daughter's college fund.
