Yellowstone should accelerate Rambus to 3.2GHz

The memory manufacturer Rambus presented the so-called Yellowstone technology at its Rambus Developer Forum. This is a process in which, instead of the previous Double Data Rate (DDR), ODR (Octal Data Rate), i.e. the transmission of eight bits per clock, is used.

The memory itself is supposed to run at 400MHz clock frequency as before, however, thanks to the ODR technology with 3.2GHz, it should virtually achieve a frequency four times higher than the previous Rambus memory with DDR. However, this innovation seems to be associated with higher costs, since Rambus has now also introduced new differential lines with DRSL (Differential Rambus Signaling Levels), which again negate a major advantage in production. Instead of the previous 16 lines, 32 lines are now required due to the additional DRSL signals. The memory bandwidth that a Rambus module could deliver with this technology would theoretically be a gigantic 6.4GB/s.
