Fifty years ago, DRAM inventor and IEEE Medal of Honor recipient Robert Dennard created what essentially became the semiconductor industry’s path to perpetually increasing transistor density and chip performance. That path became known as Dennard scaling, and it helped codify Gordon Moore’s postulate about device dimensions shrinking by half every 18 to 24 months. For decades it compelled engineers to push the physical limits of semiconductor devices. But in the mid-2000s, when Dennard scaling b...
