The smallest memory in the world

IBM Almaden Laboratories scientists have developed the world's smallest magnetic memory module. It consists of only 12 iron atoms. The module will be used to miniaturize existing magnetic storage devices. The entire module was built using a scanning tunneling microscope located in the IBM laboratory in Zurich. The data were also stored through a tunneling microscope. This will provide a solution for future quantum computers. The development of such a manufacturing process became necessary because quantum physics determined that the magnetic field of each bit, when creating memory at the atomic level, would affect an adjacent bit field, making it difficult to maintain its assigned states of 0 or 1.
