"Soon after the announce of Intel's i845D chipset it became evident that the era of RDRAM is coming to an end. The release of i845E and i845PE only strengthened this assumption. As a result, the grounds of RAMBUS turned looking quite sad: one day to the next, the new dual-channel DDR systems will overcome the combination i850+RDRAM at performance and the company may have nothing to sell (or deduct royalties for)."
