Re: RMBS has the patent on DDR No, it doesn't. DDR was in active use decades before Rambus existed. Rambus has patents on a narrowly defined combination of industry standards, none of which they invented. Rambus will collect royalties for 0 years if they lose in court or 2 to 3 years if they win and the combination of technologies used must be changed by the industry. 3 years from now, not only will RDRAM be dead, but Rambus inc. as well. And it may be much, much, sooner. Dan

mishedlo, 1)RMBS has the patent on DDR Maybe we should start wording this as "RMBS has a patent on DDR". Or at best, "some patents on DDR." Just a thought. Dave

<Show me ANY proof that RDRAM is UNSTABLE.> To be accurate, RDRAM as such could be rock-stable. The problem is that PCs need many RDRAM chips to satisfy Microsoft requirements and other bloatware. Rambus system cannot reliably work with 3 RIMM. To make it work, the 3-rd slot was eliminated in all board designs. This is the fact. Working "irreliably" means "unstable", don't you agree? Another fact: Intel Or840 board was unstable when using certain combinations of RIMMs for the whole year, without any fix. The reason for multiple RIMMs to be unstable lies in fundamental physics of transmission lines with multiple impedance-mismatched T-junctions. RAMBUS tries to fix these instabilities with unbearably tight specifications on every design detail, which drives up the total cost of RIMMs and systems. Now you might be better equipped to understand why the cost of Rambus system will be _always_ significantly higher than equivalently performing SDRAM/DDRAM system.
