  • Methods of forming magnetic memory devices
    Patent number: 7799581
    Abstract: Methods for creating a memory device can include depositing a sense layer, patterning the sense layer to form a plurality of magnetic data cells, depositing a separation layer over the plurality of data cells, depositing a reference layer over the separation layer, and patterning the reference layer to form an elongated magnetic reference cell wherein the elongated magnetic reference cell extends uninterrupted along more than one of the plurality of magnetic data cells.
    Type: Grant

    Date of Patent: September 21, 2010
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Thomas C. Anthony, Darrel R. Bloomquist, Judy Bloomquist, legal representative, Manoj K. Bhattacharyya
  • Irregular surfaced tape guide
    Patent number: 7506836
    Abstract: A tape guide that has textured surface over which the tape passes. The textured surface has a surface roughness exceeding the flying height of the tape above the surface. This new irregular surface topography reduces the air bearing and allows limited contact between the tape guide and the tape while minimizing tape distortion that can occur with other surface topographies.

  • Method of providing multiple logical bits per memory cell
    Patent number: 7019381
    Abstract: A semiconductor substrate is provided over which electrically conductive columns are formed along with electrically conductive rows crossing over the electrically conductive columns. A plurality of memory components are formed each having a resistance value corresponding to multiple logical bits and non-volatile memory cells are each formed by connecting a memory component between an electrically conductive row and an electrically conductive column.
