Scientists Create the Densest Chip Ever

Scientists have built a tiny memory chip that uses new technology to pack a relatively large amount of information into a square about one-2,000th of an inch on a side. Although the chip is modest in capacity — with 160,000 bits of information — the bits are crammed together so tightly that it is the densest chip ever made. The achievement points to a possible path toward continuing the exponential growth of computing power even after current silicon chip-making technology hits fundamental limits in 10 to 20 years
