    Abstract: A method for fabricating a magnetoresistive random access memory (MRAM) device having a plurality of memory cells includes: forming a fixed magnetic layer having magnetic moments fixed in a predetermined direction; forming a tunnel layer over the fixed magnetic layer; forming a free magnetic layer, having magnetic moments aligned in a direction that is adjustable by applying an electromagnetic field, over the tunnel layer; forming a hard mask on the free magnetic layer partially covering the free magnetic layer; and unmagnetizing portions of the free magnetic layer uncovered by the hard mask for defining one or more magnetic tunnel junction (MTJ) units.

    Abstract: An apparatus and methods for a non-volatile magnetic random access memory (MRAM) device that includes a word line, a bit line, and a magnetic thin film memory element located at an intersection of the word and bit lines. The magnetic thin film memory element includes an alloy of a rare earth element and a transition metal element. The word line is operable to heat the magnetic thin film memory element when a heating current is applied. Heating of the magnetic thin film memory element to a predetermined temperature reduces its coercivity, which allows switching of the magnetic state upon application of a magnetic field. The magnetic state of the thin film element can be determined in accordance with principles of the Hall effect.

    Abstract: A method for determining a search pattern for use in fractional motion estimation for video compression includes selecting a search center within a current macroblock; selecting a plurality of search points forming a half-pel search pattern surrounding the search center, and further selecting another search point at the search center; calculating a cost value for each search point according to a first cost function; and selecting a quarter-pel search pattern according to the cost values of at least two search points, the half-pel search pattern and the quarter-pel search pattern forming the search pattern. The search pattern is used in a matching process to determine a similarity of the current macroblock to a reference macroblock in a video undergoing compression.

    Abstract: A hinge member includes a rotatable cam element with a first cam face and a slidable cam element with a second cam face associated with the first cam face in such a manner that the second cam face moves away from the first cam face when the slidable cam element is cammed by the rotatable cam element due to an applied external force. A biasing member is connected to the slidable cam element so as to accumulate a returning force when the second cam face moves away from the first cam face and so as to urge the second cam face to move toward the first cam face when the external force ceases to be applied on the rotatable cam element.

    Abstract: A ribbon dispenser includes a body with a front cover. A cylinder is rotatably located in the body and has multiple chambers in which ribbons are received. An inlet is defined through the rear end of each chamber. A striking unit is located in the body and located behind the cylinder to introduce air into the chambers via the inlets. A revolving unit is connected to the cylinder to revolve the cylinder. A rigger is pivotably connected to the body has a driving portion to drive the striking unit. A stud protrudes from one side of the trigger so as to drive the revolving unit. The ribbons are ejected out from the body when the striking unit introduces air into the chambers. The cylinder is revolved to allow the ribbons in each room are ejected in sequence.

    Abstract: A boron or boron containing dusting layer such as CoB or FeB is formed along one or both of top and bottom surfaces of a free layer at interfaces with a tunnel barrier layer and capping layer to improve thermal stability while maintaining other magnetic properties of a MTJ stack. Each dusting layer has a thickness from 0.2 to 20 Angstroms and may be used as deposited, or at temperatures up to 400° C. or higher, or following a subsequent anneal at 400° C. or higher. The free layer may be a single layer of CoFe, Co, CoFeB or CoFeNiB, or may include a non-magnetic insertion layer. The resulting MTJ is suitable for STT-MRAM memory elements or spintronic devices. Perpendicular magnetic anisotropy is maintained in the free layer at temperatures up to 400° C. or higher. Ku enhancement is achieved and the retention time of a memory cell for STT-MRAM designs is increased.
