>"Using a combination of electrical measurements and atomic-scale measurements guided by quantum mechanics, the team found a sweet spot between stability and switch ability that yielded the dual diode+memory resistive RAM memory at a microscopic scale" Engineering is all about finding the "sweet spot"... Not too much, and not too little, but the point at which competing concerns balance...
