Just noticed that the press release was from 2012- DOH! Oh well.

The Claremont Architecture mentioned was being talked about as the IA in 2012. It grew out of the Atom processors that ran in this near threshold/sub threshold region. Lot of companies have used techniques like this for decades. Most digital stuff that runs at these absurd low voltages is subthreshold or near. The very low power Microchip (nanoWatt XLP) parts use these techniques. Intel's FINFET operate below .7v already. There was a startup called SuVolta that was based on these techniques- it disappeared (acquired or folded?) about five years ago. Freescale had some dynamic power stuff that played games with the "body" or substrate connection to modulate threshold voltage. It let them make parts that operate in strong inversion at high speeds with higher class A type leakage currents but could downshift to a slower, low leakage mode by manipulating the body voltage. They could do this on the fly- don't know what happened to it- good fodder for ISSC conferences of the day. Press releases are written by investor relations guys that don't have a firm handle on the technology and mainly into promotion. Ironically, the old 40 or so nm process nodes were much better in these respects. I think 7 nm might have overshot the mark. Take Care- Regards, John M.
