A magnetic random access memory includes a memory cell including a first fixed layer, a second fixed layer, and one or more free layers disposed between the first fixed layer and the second fixed layer. The first and second fixed layers are continuous layers and commonly shared by a plurality of memory cells. The magnetic random access memory has a relatively simple structure that not only reduces magnetic interference between memory cells, but also simplifies the fabrication process and increases the integration level.

Device and method for disturbance free 3D MRAM fabrication

A magnetic random access memory and its manufacturing method related to semiconductor techniques. The magnetic random access memory comprises a word line, a bit line, and a memory unit positioned between the word line and the bit line, wherein the memory unit comprises a fixture layer connecting the bit line, a free layer connecting the word line, and an insulation layer positioned between the fixture layer and the free layer. This magnetic random access memory has a simpler design than conventional devices and can be manufactured more easily, which improves the integrity of the manufacturing process.
