Scientist gets a billion pages on one chip

Future solid state disks may finally be able to catch up with the large capacities of mechanical hard drives, thanks to an ingenious project by a scientist at the North Carolina State University. Dr Jay Narayan has developed a silicon storage chip that stores data in magnetic nanodots, or quantum dots; tiny structures that can measure just 6nm in diameter. Each nanoscale dot stores a single bit of data, but you can squeeze so many dots onto a small area of silicon that...
