Abstract: Material layer stack structures to provide a magnetic tunnel junction (MTJ) having improved perpendicular magnetic anisotropy (PMA) characteristics. In an embodiment, a free magnetic layer of the material layer stack is disposed between a tunnel barrier layer and a cap layer of magnesium oxide (Mg). The free magnetic layer includes a Cobalt-Iron-Boron (CoFeB) body substantially comprised of a combination of Cobalt atoms, Iron atoms and Boron atoms. A first Boron mass fraction of the CoFeB body is equal to or more than 25% (e.g., equal to or more than 27%) in a first region which adjoins an interface of the free magnetic layer with the tunnel barrier layer. In another embodiment, the first Boron mass fraction is more than a second Boron mass fraction in a second region of the CoFeB body which adjoins an interface of the free magnetic layer with the cap layer.

Abstract: A 1S-1T ferroelectric memory cell is provided that include a transistor and a two-terminal selector device. The transistor exhibits a low conductive state and a high conductive state (channel resistance), depending on drive voltage. The two-terminal selector device exhibits one of an ON-state and an OFF-state depending upon whether the transistor is in its low conductive state or its high conductive state. The transistor may be, for instance, a ferroelectric gate vertical transistor. Modulation of a polarization state of ferroelectric material of the vertical transistor may be utilized to switch the state of the selector device. The memory cell may thus selectively be operated in one of an ON-state and an OFF-state depending upon whether the selector device is in its ON-state or OFF-state.

Abstract: Embedded non-volatile memory structures having an independently sized selector element and memory element are described. In an example, a memory device includes a metal layer. A selector element is above the metal layer. A memory element is above the metal line. A spacer surrounds one of the selector element and the memory element having a smallest width, and wherein the one of the selector element and the memory element not surrounded by the spacer has a width substantially identical to the spacer and is in alignment with the spacer.
