North Carolina State University's Jay Narayan led a research effort to create a computer chip that has enough memory to store all the information in a library. The chip uses nanodots, or nanoscale magnets, which are made of single, defect-free crystals and can be as small as six nanometers in diameter. The nanodots are integrated directly into a silicon chip. Their precise orientation enables programmers to reliably read and write data to the chips.

"We have created magnetic nanodots that store one bit of information on each nanodot, allowing us to store over one billion pages of information in a chip that is one square inch," Narayan says. He says the chip can be manufactured at an affordable cost. Narayan wants to develop magnetic packaging that would enable lasers or other technologies to interact with the nanodots.
