I will remind you of it, because I expect a lot more from you. Did you even bother to read the voluminous documentation on DDR signalling? Since it's an industry group promoting DDR, there is plenty of public information about it, complete with worst case data, oscilloscope images and simulation results. Unlike Rambus, the companies doing DDR are very experienced in this industry. They are responsible for most of the memory and chipsets currently shipping. That's a hell of a lot of companies, and a hell of a lot of engineers. (Note that VIA took a lot of Intel's market share over the PC133 issue.) Why do you think they don't know what they're doing? Next thing, you're probably going to go off on how AMD can't make processors (or motherboards) and now memory architectures that work right. Okay. Where's the Intel 1.13GHz Pentium? Where's the SDRAM memory converter for the i820? AMD is executing beautifully, and so is VIA, but there are several dozen other companies that are betting hard that DDR will run beautifully. -- Carl P.S. So you want to get educated?
