Re: <"being able to leave more pages open simultaneously"...what does this refer to?>

This is one of rambus' biggest plusses (right after saving pins). In drdram memories the cells are grouped into many separate banks which can be accessed independently. In tradional drams you always have faster column or page access time than row access time. In drdram it is like having many "columns open" at the same time although they are called banks or pages. You can have between 4 and 16 (I think) banks open at the same time in each drdram chip. Therefore you get a much larger fraction of fast accesses.

How much faster is hard to tell. I think that the world will argue over this for years and we won't really know until someone proves optimum chip sets for both memories -- which it sounds like Camino does not do!

I hope that this explanation was comprehensible.
