<< Two DDR SDRAM "channels" will cost a boat-load of pins, not just a measly 30 pins, more like 100 pins. Yes you can build a dual DDR controller, but it may bump you into a significantly more expensive package. >> What's the price per pin though, say it is 100 more pins. Let's say a pin costs 10 cents (over double the price most people quote, but just to show worst case scenario). That's $10 more in parts. Maybe some design complexity, and economy of scale works against you (low volume high end part at first) and another $30 bucks gets pushed onto the user. It's still hundreds cheaper for the solution than the rambus solution that would replace it. Now if dual rambus channels on a willy with a 400mhz bus trounces dual channel DDR that's one thing, but if it only plays on par, the dual ddr board+ram would still be a much cheaper solution unless there is another huge drop ($100+) in rambus prices (and that's assuming the 600mhz stuff will be good enough).
