So assuming a june 2012 release, what does history suggest as the timeframe of widespread adoption in the PC industry.

Please tell me that RAMBUS is not a memeber of this working group! Also is RAMBUS going to be filing law suits against all manufacturers?

Rambus left JEDEC years ago and then JEDEC proceeded to steal all of rambus patented designs. I will bet there's (stolen) Rambus tech in DDR4.

Is CRC going to impact latency or thruput? Would anyone use non-ECC memory architecture at these lithographies? Many questions...

@fdunn: I would be surprised if RAMBUS does not collect royalties for each DDR4 chip sold. With Qimonda gone, Micron and Elpida fading, we will be left with a Samsung-Hynix Korean duopoly. DDR4 may be the last JEDEC spec. Samsung and Hynix can just make their own spec and force it on the market.

If there's Rambus tech being used in DDR4 they should get paid but Hynix and Micron has a history of stealing patented designs. Hynix paid a huge fine to DOJ and employees went to jail for it. Micron rolled over and got leniency even though they were the ring leader. Maybe DOJ one day will wake up and understand this but i doubt it, Micron has to many influential people in their pocket.

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
