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

DARPATEE

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…...
