Patent abstract
A memory device includes a fixed magnetic layer, a tunnel barrier layer over the fixed magnetic layer, and a free magnetic structure formed over the tunnel barrier layer, wherein the free magnetic structure has layers or sub-layers that are weakly magnetically coupled. Thus, a low programming voltage can be used to avoid tunnel barrier breakdown, and a small pass transistor can be used to save die real estate.
