Patent ID: 8217477

Claim:
A magnetic memory cell comprising: a magnetoresistive device including a first non-magnetic film, a ferromagnetic free layer and a ferromagnetic pinned layer, the ferromagnetic free layer and the ferromagnetic pinned layer being formed with the first non-magnetic film interposed in between; an electrode for causing a current to flow in the magnetoresistive device in its thickness direction; a non-magnetic layer formed on and connected to the ferromagnetic free layer; and a ferromagnetic interconnection connected to the non-magnetic layer and formed on the non-magnetic layer at a position that is laterally offset from the magnetoresistive device, wherein information is written in the magnetic memory cell by causing the a current to flow in the magnetoresistive device so that a spin transfer torque switches a magnetization of the ferromagnetic free layer, and a magnetization direction of the ferromagnetic interconnection is antiparallel to a magnetization direction of the ferromagnetic pinned layer.
