    摘要: A planar silicon magnetoresistive read/write head has separate read and write gaps that can be individually optimized. The write gap includes a write gap shunt that suppresses signals that are read across the write gap without interfering with the ability of the head to generate write signals at the write gap. The head retains both the advantages of removing the magnetoresistive element from the air bearing surface to avoid wear, shorting, and corrosion, and to eliminate cross-track asymmetry, associated with dual gap magnetoresistive heads; and the advantages of low cost fabrication and high area density, associated with silicon planar head structures.

    摘要: Providing a magnetic head with a yoke and a gap structure coupled to a substrate that is positioned above a magnetic medium. The gap structure includes one or more lips, a first and a second ferromagnetic pole, and a magnetoresistive element (MRE). The magnetoresistive element is removed from the air-bearing surface of the magnetic head. For the embodiment with two lips, the two lips define a head gap. Each ferromagnetic pole is connected to one lip. The two poles are separated by a distance greater than the length of the gap, and each pole has a thickness that is greater than the thickness of each lip. The MRE is substantially coupled magnetically, but not electrically to the two poles at a location where the two poles are separated by a distance greater than the length of the gap.

    摘要: The invention includes a method of providing magnetic stability of a memory cell. The memory cell is generally located proximate to a conductive line, and proximate to a write mechanism that can set a magnetic state of the memory cell. The method includes receiving a representation of a maximum magnetic field intensity available from the write mechanism. A desirable placement of the memory cell relative to the conductive line can be generated for providing stability of the memory cell, while still allowing the write mechanism to change the magnetic state of the memory cell.

    摘要: A memory device includes a memory array having a substrate, an array of memory cells disposed over the substrate, row conductors coupled to the memory cells, and column conductors coupled to the memory cells. The memory device also includes current sources that generate variable write currents in response to temperature changes in the memory array. The variable write currents are generated to accommodate the change in coercivities of the memory cells as the temperature of the array changes. A current source can include a temperature sensor that provides a continuous, immediate output to the current sensor to ensure accurate adjustment of a write current generated by the current source. There is no need to halt operation of the memory device to calibrate the current source. In addition, the current source provides an accurate adjustment to the write current because the temperature used by the temperature sensor to generate the output may be taken contemporaneously with generation of the write current.
