Abstract
A non-volatile latch having a power supply terminal and a ground terminal is disclosed. The non-volatile latch includes a pair of cross-coupled inverter elements each having a power supply terminal and a ground terminal. Magneto-resistive elements are interposed between the power supply terminals of both cross-coupled inverter elements and the power supply terminal of the non-volatile latch. In addition, magneto-resistive elements are interposed between the ground terminals of both cross-coupled inverter elements and the ground terminal of the non-volatile latch. By including magneto-resistive elements in each supply line, the effects of transistor parameter variation can be minimized.
