Documentary Dish. Atomic-scale magnetic memory. The world's smallest bit Scientists from IBM Research have been investigating and controlling matter on an atomic scale for decades.
So, naturally, their latest quest would involve greatly decreasing the storage capacity needed for one bit of data, which on today's computers stands at about 1 million atoms. They set out to develop the ultimate memory chips of the future. Starting at the very beginning of density—single atoms—they created the world’s smallest magnetic memory bit and answered the question of how many atoms it takes to reliably store one bit of magnetic information at a low temperature: 12. By studying the behavior of atoms, researchers can identify crucial factors for building smaller, faster and more energy-efficient devices for business and consumers. Physics Today.
