New material stores four magnetic states per cell – exponentially increasing memory storage

New material stores four magnetic states per cell – exponentially increasing memory storage

Every text message, photograph, and saved file still comes down to a simple bargain: information is stored as either 0 or 1. That binary system built modern computing, and for decades engineers kept improving it by shrinking the transistors that carry and store those bits. That long run is getting harder to sustain. As components approach physical limits, researchers are looking for other ways to handle information, including methods that do not…
