Hi Ali Chen; I might as well beat John Walliker to the punch regarding high impedance of RDRAM outputs...

John's right. Instead of the traditional low impedance voltage drivers, Rambus uses high impedance current drives. This, of course, is why the voltages look like Hell during reads. In particular, this chaos obtains at the driver.

The high impedance drivers idea was another one of the bad ideas used in RDRAM. And by the way, at the same time as they reduced the supply voltage for the part, they also decided to switch from voltage mode outputs to current mode outputs, thus increasing the output compliance range problem.

Re: Let me remind you that the difference between practice and theory is much bigger in practice than in
theory.

I suppose I've heard it before, but I remain

Still laughing!

P.S. The tone of my post was intentionally aggressive,
for the sake of delivering the point to slow members.
Do not feel personally offended:).

Not aggressive; obnoxious. Must go with being a bear. What a screwed up attitude you have. If you want to counter someone's argument, obnoxiousness is sure way to make sure they pay no attention to your arguments at all. Of course, sometimes that's useful when your arguments are invalid.
