Computer and memory chips usually tend to get smaller over time, but a paper published Thursday in Science, IBM details how it’s building memory chips that would be 100 times more dense than today’s hard drives by starting with the smallest building blocks: atoms. Big Blue’s prototype chip is only 12 atoms across (click here for an awesome visualization of how small an atom is. No really, click it!) but is another way of thinking about ways to get beyond the limits of building ever-smaller chips keeping Moore’s Law on track.
Andreas Heinrich, the project lead for IBMs efforts, explained in an interview that this tech may never be realized in part because it requires an entirely new type of manufacturing equipment to be built. However, IBM is learning how to manipulate atoms for storing bits and identified a new type of magnetism that could one day be used. Unlike the type of magnetism that keeps your magnets stuck to your fridge, IBM is looking at the reverse of those properties to make this highly dense type of memory.
