IBM's 32nm eDRAM process was announced in 2009, but the question it would be interesting to know the answer to is WHAT "IBM chips with 32nm eDRAM on SOI" will GF be manufacturing ... which I doubt we will learn.
These can't be Power7 ... that's 45nm, and I doubt IBM would farm those out in any event. These are likely IBM-contracted merchant ASICs , and what they are and where they are going and why IBM is willing to see GF fab them is the interesting story as I see it ... all details we'll likely not be told.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
