Magnetic memory device and method of manufacturing the same

摘要

The device has a magnetoresistance unit to store information. A wiring is provided along a direction to apply a magnetic field to the magnetoresistance unit. A surface faces the magnetoresistance unit and another surface is placed opposite to the former surface. The former surface is in smaller width than the latter surface. The cross-section of the wirings is larger to their lateral dimension. An independent claim is also included for a method of manufacturing a magnetic memory device.
