Although I'm not sure if there is still a company out there that will want to work with Rambus (apparently there is - although just for having a legal dispute years later), CNet has posted details on their next year plans for XDR DRAM technology.

[COLOR=royalblue]The XDR DRAM technology (formerly code-named Yellowstone) will transfer data at 3.2GHz initially, rising to 6.4GHz in the future--much faster than memory available now. In effect, that means XDR DRAM, which will be manufactured by partners Toshiba and Elpida, should ultimately be capable of transferring 100GB of data per second.[/COLOR]
