METHOD FOR SWITCHING OUT-OF-PLANE MAGNETIC TUNNEL JUNCTION CELLS INCLUDING A FREE LAYER, A BARRIER LAYER, AND A REFERENCE LAYER

摘要

PURPOSE: A method for switching out-of-plane magnetic tunnel junction cells is provided to read or sense a resistance of an MTJ(Magnetic Tunnel Junction) cell by including a DC current source electrically connected to the MTJ cell.;CONSTITUTION: An AC switching current is passed through an out-of-plane magnetic tunnel junction cell(505). An AC switching current switches a magnetization orientation of a ferromagnetic free layer. A frequency of the AC switching current is matched with a gyromagnetic frequency of the ferromagnetic free layer. The AC switching current induces a magnetic field circumnavigating the magnetic tunnel junction cell.;COPYRIGHT KIPO 2012
