US Patent 10438995 Devices including magnetic tunnel junctions integrated with selectors

A Magnetic Tunnel Junction (MTJ) device can include an array of cells. The array of cells can include a plurality of source lines disposed in columns, set of selectors coupled to respective source lines, MJT structures coupled to respective selectors and a plurality of bit lines disposed in rows and coupled to respective sets of MTJ structures. The array of cells can also include buffers coupled between respective selectors and respective MTJ structures. In addition, multiple arrays can be stacked on top of each other to implement vertical three-dimensional (3D) MTJ devices.
