  • Patent number: 11295884
    Abstract: A perpendicular spin transfer torque memory (pSTTM) device incorporates a magnetic tunnel junction (MTJ) device having a free magnetic stack that includes a plurality of magnetic layers interleaved with a plurality of non-magnetic insert layers. The layers are arranged such that the topmost and bottommost layers are magnetic layers. The stacked design decreases the damping of the MTJ free magnetic stack, beneficially reducing the write current required to write to the pSTTM device. The stacked design further increases the interface anisotropy, thereby beneficially improving the stability of the pSTTM device. The non-magnetic interface layer may include tantalum, molybdenum, tungsten, hafnium, or iridium, or a binary alloy containing at least two of tantalum, molybdenum, tungsten hafnium, or iridium.

  • Patent number: 11250899
    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.
