  • Patent number: 6573713
    Abstract: A transpinnor switch is described having a network of thin-film elements in a bridge configuration, selected ones of the thin-film elements exhibiting giant magnetoresistance. The switch also includes at least one input conductor inductively coupled to a first subset of the selected thin-film elements, and a switch conductor inductively coupled to a second subset of the selected thin-film elements for applying magnetic fields thereto. The switch is configurable using the switch conductor to generate an output signal representative of an input signal on the input conductor. The switch is also configurable using the switch conductor to generate substantially no output signal regardless of whether the input signal is present. The transpinnor switch described herein may be used in a wide variety of applications including, for example, a field programmable gate array.
