20080278860 | EXTRAORDINARY MAGNETORESISTIVE (EMR) DEVICE WITH NOVEL LEAD STRUCTURE - An extraordinary magnetoresistive sensor (EMR sensor) having reduced size and increased resolution is described. The sensor includes a plurality of electrically conductive leads contacting a magnetically active layer and also includes an electrically conductive shunt structure. The electrically conductive leads of the sensor and the shunt structure can be formed in a common photolithographic masking and etching process so that they are self aligned with one another. This avoids the need to align multiple photolithographic processing steps, thereby allowing greatly increased resolution and reduced lead spacing. The EMR sensor can be formed with a magnetically active layer that can be close to or at the air bearing surface (ABS) for improved magnetic spacing with an adjacent magnetic medium of a data recording system. | 11-13-2008 |

20090190269 | SELF-ALIGNED COPLANAR STRUCTURE FOR NARROW-TRACK EMR DEVICES AND A METHOD FOR PRODUCING THE SAME - An extraordinary magnetoresistive sensor (EMR sensor) having a lead structure that is self aligned with a magnetic shunt structure. To form an EMR sensor according to an embodiment of the invention, a plurality of layers are deposited to form quantum well structure such as a two dimensional electron gas structure (2DEG). A first mask structure is deposited having two openings, and a material removal process is performed to remove portions of the sensor material from areas exposed by the openings. The distance between the two openings in the first mask defines a distance between a set of leads and the shunt structure. A non-magnetic metal is then deposited. A second mask structure is then formed to define shape of the leads. | 07-30-2009 |

20110149632 | MULTILEVEL FREQUENCY ADDRESSABLE FIELD DRIVEN MRAM - A three-dimensional nonvolatile memory array device includes a plurality of memory elements and a memory controller. The plurality of memory elements each have a stack of a plurality of bits, which in turn each include a magnetic free layer, a magnetic pinned layer, and a non-magnetic layer. The magnetic free layer is configured to alternate its magnetization orientation based on a radio frequency current being at a resonant frequency of the magnetic free layer and on a magnetic field being applied to the magnetic free layer. The magnetic pinned layer has a specific magnetization orientation. The non-magnetic layer is located in between the magnetic free layer and the magnetic pinned layer. The memory controller is in communication with each of the plurality of memory elements, and configured to write data to and read data from the plurality of bits in the memory elements. | 06-23-2011 |
