Abstract
A double-decker MRAM cell is provided, including a stacked structure of first and second magnetic tunnel junctions. Each magnetic tunnel junction includes free and fixed magnetic regions made of magnetic material separated by a tunneling barrier layer made of non-magnetic material. The fixed magnetic regions are pinned by at least one pinning layer made of the same antiferromagnetic material such that in applying an external magnetic field fixed magnetizations are brought into a scissored configuration.
