Remember Rambus? That's right, they are still around(example: Nintendo!), and Steven Woo, an engineer for Rambus, spills info in an interview with
Dailytech, talking about next-gen memory and what it could bring to PCs. Among the most interesting things discussed was the better scaling in terms of losing capacity for higher speeds that FB-DIMM can provide in the future, which although was only referenced to for servers could eventually apply to all new memory. The technology sounds interesting, and since it will be available on a wider (and probably cheaper) scale than RDRAM was, it's a possibility we may see it being used to apply DDR-3 or even DDR-2 for desktop systems. We'd all definitely like to hear more about how serial access for RAM could help improve both speed and capacity, so it's something to keep your eyes out for.
