  • NONVOLATILE MEMORY CROSSBAR ARRAY
    Publication number: 20170271410
    Abstract: Provided in one example is a nonvolatile memory crossbar array. The array includes a number of junctions formed by a number of row lines intersecting a number of column lines; and a resistive memory element in series with a selector at each of the junctions coupling between one of the row lines and one of the column lines. The selector may be a volatile switch including: a bottom electrode; an oxide layer disposed over the bottom electrode, the oxide layer including Cu2O; and a top electrode disposed over the oxide layer.

  • Fabrication of magnetic tunnel junctions with epitaxial and textured ferromagnetic layers
    Patent number: 7450352
    Abstract: This invention relates to magnetic tunnel junctions and methods for making the magnetic tunnel junctions. The magnetic tunnel junctions include a tunnel barrier oxide layer sandwiched between two ferromagnetic layers both of which are epitaxial or textured with respect to the underlying substrate upon which the magnetic tunnel junctions are grown. The magnetic tunnel junctions provide improved magnetic properties, sharper interfaces and few defects.
