Abstract:
A non-volatile latch having a first supply terminal and a second supply terminal, the non-volatile latch comprising:a latching element having a first inverting logic element and a second inverting logic element coupled together in a cross-coupled configuration, wherein each of the first and second inverting logic elements has a power supply terminal and a ground terminal;first magnetic means for providing a first magnetically programmable resistance value, the first magnetic means connected between the power supply terminal of the first inverting logic element and the first supply terminal of the latch;second magnetic means for providing a second magnetically programmable resistance value, the second magnetic means connected between the ground terminal of the first inverting logic element and the second supply terminal of the latch;third magnetic means for providing a third magnetically programmable resistance value, the third magnetic means connected between the power supply terminal of the second inverting logic element and the first supply terminal of the latch; andfourth magnetic means for providing a fourth magnetically programmable resistance value, the fourth magnetic means connected between the ground terminal of the second inverting logic element and the second supply terminal of the latch.
