Hi Zeev Hed; Re Jazio vs Rambus technology... Jazio has got a lot of exposure at DDR forums. Here's their website, click around on it, they are providing a simple technique for getting 2GHz signals out of current SDRAM structures: jazio.com Rambus did not come up with a radical new technology for sending signals down a wire. All they did was apply high speed techniques to memory, with some modifications to make it work in CMOS. But they really didn't provide any new technology that had not previously appeared in CMOS. The new Rambus idea, 4-level signalling, is probably not going to see the light of day, my guess, it just doesn't provide much advantage compared to the headaches involved. All the stuff that Rambus thought was their brilliant ideas for modern memory turned out to be useless except for the latency register. They didn't even suggest the modern use of the latency register in their original patents, but that is the one piece of IP that the memory people are worried about. Their original use of the latency register was to allow for different time of flight from RAM to controller. The JEDEC use is to provide for differences in speed grades in SDRAM production, time of flight doesn't enter into it. Apparently, neither they nor JEDEC thought that the Rambus patents applied to SDRAM's use of that register. But Rambus got the patent examiners to explicitly apply their patent to the SDRAM technology, and now we have a big patent fight. -- Carl
