I was seriously hoping a while back, WAYYYY back when I first heard word that Rambus was going to sue everyone, before it made news, (back in like 2003) that the courts would laugh at them, and tell them that they really COULDN'T literally "own everything" when it came to what we know of as RAM today.
Apparently, I overestimated the intelligence of judges. After all, they somehow allow ridiculous patents like those on HUMAN GENES to stand, so it's only natural that they'd consider patents on, say, double-pumping memory signals to be fully enforceable. Never mind that it wasn't Rambus' invention; I know that Intel had introduced the double-pumped (later quad- and octo-) AGP port in 1997, three years before DDR-SDRAM showed up.
So this is very troubling news for the ENTIRE computing industry. This won't be just memory makers, nVidia, and ATi. If this keeps up, we'll see AMD's processor section, as well as Intel, be targetted.
