Here is a bit more information on how this architecture works:

The 3D design enables scientists to interweave memory, which stores data, and the number-crunching processors in the same tiny space, said Max Shulaker, one of the designers of the chip, and a doctoral candidate in electrical engineering at Stanford University in California.

Reducing the distance between the two elements can dramatically reduce the time computers take to do their work, Shulaker said Sept. 10 here at the “Wait, What?” technology forum hosted by the Defense Advanced Research Projects Agency, the research wing of the U.S. military.

This is indeed a “Wait, What?” design.  What types of applications would they use this for?

Feel free to comment.
