Patent ID: 7791941

Claim:
A static random access memory (SRAM), comprising: a cross coupled pair of inverters, wherein each inverter includes a p-type pull up transistor and an n-type pull down transistor coupled to a first static storage node, wherein gates of each inverter in the pair are coupled to the first static storage node of the other inverter; and wherein each inverter includes a second non-volatile storage node coupled to the first static storage node, wherein the second storage node comprises a two terminal magnetic tunnel junction (MTJ) device, wherein the MTJ device includes: a first unpinned ferromagnetic layer coupled to the first storage node such that a polarization of an associated spin value can rotate; and a second pinned ferromagnetic layer in contact with an anti-ferromagnetic layer coupled to a control line such that a polarization of an associated spin value is fixed in one direction; wherein the first unpinned ferromagnetic layer and the second pinned ferromagnetic layer are separated by a dielectric.
