    摘要: Embodiments relate to magnetoresistive (xMR) sensors. In an embodiment, an xMR stack structure is configured to form two different xMR elements that can be coupled to form a locally differential Wheatstone bridge. The result is a highly sensitive magnetic sensor with small dimensions and robustness against thermal drift and sensor/encoder pitch mismatch that can be produced using standard processing equipment. Embodiments also relate to methods of forming and patterning the stack structure and sensors that provide information regarding direction in addition to speed.

    摘要: According to an embodiment, an integrated circuit includes a magneto-resistive memory cell. The magneto-resistive memory cell includes: a first ferromagnetic layer; a second ferromagnetic layer; and a nonmagnetic layer being disposed between the first ferromagnetic layer and the second ferromagnetic layer. The integrated circuit further includes a programming circuit configured to route a programming current through the magneto-resistive memory cell, wherein the programming current programs the magnetizations of the first ferromagnetic layer and of the second ferromagnetic layer by spin induced switching effects.

    摘要: A magneto resistive memory device is fabricated by etching a blanket metal stack comprised of a buffer layer, pinned magnetic layer, a tunnel barrier layer and a free magnetic layer. The problem of junction shorting from resputtered metal during the etching process is eliminated by formation of a protective spacer covering the side of the freelayer and tunnel barrier interface. The spacer is formed following the first etch through the free layer which stops on the barrier layer. After spacer formation a second etch is made to isolate the device. The patterning of the device tunnel junction is made using a disposable mandrel method that enables a self-aligned contact to be made following the completion of the device patterning process.
