Where is the Rambus used on is it used for PC memory as in RAM?
Yes, RAMBUS is used as RAM. There are different types of RAM. SDR (Single Data Rate) is your normal PC33/66/100/133. DDR (Double Data Rate) is better because works on both the rise and fall of the clock tick. RAMBUS, I believe, is similar to DDR but very different (I know it sounds odd to put it like that). It was used on the early P4 machines but it never really took off and now most thing use DDR instead of RAMBUS.
