DARPA’s TEE program developing skyrmion based high-density and energy-efficient magnetic information storage devices

In magnetic memories, information (for example, a collection of bits) is stored as clusters of spins, which are either an up or a down (or put differently, a one or a zero). These spin clusters, which form the basis of magnetic memories, become less stable when reduced in size. Magnetic storage becomes increasingly volatile and less efficient as it decreases in size, creating significant barriers for high-performance computation and information processing. As market forces drive electronic and mechanical devices to become smaller and smaller, there is a rapidly intensifying need for high-density and energy-efficient magnetic information storage.
