Abstract

A sensing device exhibits a tunneling magneto-resistive (TMR) effect, and changes electrical resistance in response to a magnetic field. A first current carrying conductor is positioned in proximity to the TMR sensing device, such that upon an application of a sufficient current, a magnetic field is generated. The magnetic field is sufficiently strong and properly oriented so as to cause a magnetization of a soft magnetic layer of the TMR sensing device, thereby causing a change of the TMR sensing device from one bi-stable state to another bi-stable state.
