ABSTRACT:
A magnetic memory cell including a data storage layer having an easy axis and a reference layer having an orientation of magnetization which is pinned in a direction that is off-axis with respect to the easy axis. This structure increases the signal obtainable during read operation on the magnetic memory cell notwithstanding the effects of magnetizations in the edge domains of the data storage layer. In addition, this structure allows high MRAM densities to be achieved using square-shaped memory cell structures.
