IBM says you'll need 12 Atoms to hold a bit, we nod

Rather than trying to shrink current data storage technologies further, IBM took the opposite approach and designed a new system from the ground up, building it individual atoms. The new storage could lead to 100-fold increases in chip densities. Take that, Moore's Law. Researchers at IBM, in conjunction with the German Center for Free-Electron Laser Science, used a scanning tunneling microscope to line up iron atoms that comprise the magnetic storage system. They found that twelve iron atoms, assembled in two rows of six, was the minimum number necessary to stably hold a single bit of information.
