Hi Dan3; I think that the Virtual Channel is probably pretty good technology. Basically, it adds a lot of virtual rows to memory, and that saves time on row misses.

It would be especially useful on systems that had a lot of simultaneous processes or processors sharing DRAM.

The big problem is that the other players just don't seem to be supporting it much. The big solution is that NEC is making it compatible to SDRAM, so this lets big guys spec it in with less risk. If NEC drops it, they can slap in SDRAM, with some degradation in performance. And NEC will presumably move the technology along.

But I think the next big memory technology (after PC133) is pretty much going to be DDR or rambus, as they are the ones with the design wins.
