Abstract
A programmable magnetic device for generating random numbers during a programming operation, including an array of a plurality of magnetic tunnel junctions. Each magnetic tunnel junction includes a reference layer having a reference magnetization; a tunnel barrier layer; and a storage layer having a storage magnetization. The programmable magnetic device is arranged such that, during the programming operation, the storage magnetization is orientable in an unstable magnetization configuration and relaxable randomly in one of a plurality of stable or metastable configurations from the unstable magnetization configuration.
