Magnetic random access memory having a vertical write line

A magnetic random access memory (MRAM) device is formed having a fixed magnetic layer, a free magnetic layer and a first dielectric layer between them in a recess. A metal plug and an optional second dielectric layer are also formed in the recess. The metal plug serves as a write path. A word line in the MRAM cell is the gate electrode of a transistor used to both write and read the MRAM device. To write the device a current travels in a substantially vertical direction and therefore only affects one MRAM cell, thereby not affecting adjacent cells. Data storage is thereby improved.
