Hi wily; DDR-II will first ship (if it makes it that far) while DDR is still shipping, and will still be shipping after DDR is obsolete. So in a sense, DDR-II will be both a contemporary and a successor.

My guess is that 222 memory is going to be faster than 333 memory, (on average) even when the latter has one of the caching improvements. But NightOwl is the expert in that field, hopefully he will provide links to a tomshardware article comparing the technologies.

Re EDRAM and SDRAM patents. I suppose you are thinking of the Rambus situation. The most significant patent (or part of a patent) that Rambus has, IMO, is the one having to do with controllable latency. That's the feature that allows your memory to be set for different latencies just after powerup. This feature is in the JEDEC standard, and since EDRAM is a superset of JEDEC SDRAM (correct, NightOwl?) it must then include this feature. So I'm all but certain that the patent situation would apply to EDRAM equally with SDRAM.
