  • Magnetoresistive device
    Patent number: 9093163
    Abstract: A method of operating a magnetoresistive device is described. The device comprises a ferromagnetic region configured to exhibit magnetic anisotropy and to allow magnetisation thereof to be switched between at least first and second orientations and a gate capacitively coupled to the ferromagnetic region. The method comprises applying an electric field pulse to the ferromagnetic region so as to cause orientation of magnetic anisotropy to change for switching magnetisation between the first and second orientations.
    Type: Grant
    Filed: January 14, 2010
    Date of Patent: July 28, 2015

  • SINGLE-CHARGE TUNNELING DEVICE
    Publication number: 20110103138
    Abstract: A single-electron transistor (1) has an elongate conductive channel (2) and a side gate (3) formed in a 5 nm-thick layer (4) of Ga0.98Mn0.02As. The single-electron transistor (1) is operable, in a first mode, as a transistor and, in a second mode, as non-volatile memory.

  • Extended play for poker-style card games
    Publication number: 20060246978
    Abstract: Various embodiments of a method for playing a card game in association with a poker-style card game are disclosed. The method may include playing the poker-style card game to a normal ending point; permitting placement of a supplemental bet in association with the poker-style card game; dealing at least one additional card at a normal ending point of the poker-style card game in response to placement of the supplemental bet; and, factoring the additional card into the outcome of the poker-style card game.
