Abstract:
A programmable resistive circuit using magnetoresistive memory technology, comprising:a plurality of multi-state magnetoresistive memory elements;a plurality of programmable segments coupled together to form a resistive circuit having first and second terminals, each segment including at least one of the plurality of multi-state magnetoresistive memory elements and each segment having at least one control input to select its state;select logic, coupled to each of the plurality of programmable segments, that is coupled to the at least one control input of each segment of the resistive circuit to achieve a programmed resistance between the first and second terminals of the resistive circuit; anda source signal applied to the resistive circuit that generates an output signal that is a combination of signals developed by each of the plurality of multi-state magnetoresistive memory elements in the resistive circuit.
