Claim Text:
1. A magnetic random access memory (MRAM) element comprising: a first magnetic tunnel junction (MTJ) including a first magnetic reference layer and a first magnetic free layer with a first insulating tunnel junction layer interposed therebetween, said first magnetic reference layer having a first pseudo-fixed magnetization direction substantially perpendicular to a layer plane thereof, said first magnetic free layer having a first variable magnetization direction substantially perpendicular to a layer plane thereof; a second MTJ including a second magnetic reference layer and a second magnetic free layer with a second insulating tunnel junction layer interposed therebetween, said second magnetic reference layer having a second pseudo-fixed magnetization direction that is substantially perpendicular to a layer plane thereof and is substantially opposite to said first pseudo-fixed magnetization direction, said second magnetic free layer having a second variable magnetization direction that is substantially perpendicular to a layer plane thereof and is substantially opposite to said first variable magnetization direction; and an anti-ferromagnetic coupling layer that couples said first and second magnetic free layers to each other.
