"I would like to know, who, at JEDEC claims to have invented the Rambus inventions" - Jim Rockwell No one claims this. This is a wrong question. All main elements of Rambus invention were invented and made public well before Rambus, see example: Scalable Coherent Interface, published in 1988: slac.stanford.edu It contains all relevant ideas about Dual Data Rate, packet protocols, and current-steering drivers. Control registers were invented much earlier. Rambus combined the known techniques into a multiplexed interconnection, with special configuration means, called "Concurrent Rambus", or Ram-BUS-1. No one denies this. It is important to discern that the contemporary Rambus in Pentium-4 machines is not the patented Rambus-1, it is very different in its bus architecture and configuration/setup. However, it is not quite clear who actually invented the contemporary Rambus, or "Direct Rambus". True, it was originally promoted by Rambus, but with several important omissions. Currently Intel holds a patent that seems to be closest to current Rambus implementation: delphion.com US6173345:Method and apparatus for levelizing transfer delays for a channel of devices such as memory devices in a memory subsystem Hope it clears some confusions between patents and reality.

Hi Tinker, Mr Rockwell certainly doesn't mince his words. But I do find his line of reasoning a bit, how do you say it, awkward ? This is akin to telling the cop (who's caught you speeding) that everyone else is speeding too and therefore he (she?) should let you off. I wonder how well this plan works. Actually I do have some recollections of such pleadings from my early childhood :-( I am sure there is no dearth of examples. Any LSAT book will do. Oh, I am very neutral on RMBS. I haven't got the foggiest what RDRAM does and why is it any better. If I needed the speed I'd probably first upgrade my 166 Pentium MMX... Regards -Dinesh
