Magnetic memory structure with improved half-select margin

摘要

A magnetic memory with enhanced half-select margin includes an array of magnetic memory cells each having a data storage layer with an easy axis and an array of conductors each having an angle of orientation with respect to the easy axes that is preselected to enhance half-select margin in the magnetic memory. The angle of orientation is such that the longitudinal write field is enhanced and the perpendicular write field is minimized in a selected memory cell. The magnetic memory cells optionally includes a structured data storage layer including a control layer that minimizes the likelihood of half-select switching in the unselected magnetic memory cells.
