<p>A non-volatile, bistable magnetic tunnel junction (MTJ) register cell includes first and second magnetic tunnel junctions connected for differential operation. The first MTJ is coupled between an easy axis line and an output terminal and the second MTJ is coupled between an inverse easy axis line and an inverse output terminal. A hard axis line is coupled magnetically to the MTJs and an enable line is coupled to the MTJs for enabling and disabling the differential operation. The MTJ register cell can be connected as a PIPO non-volatile register, a right or left non-volatile shift register, or a multi-bit bi-directional non-volatile shift register.</p> |
