Design of a variation-resilient single-ended non-volatile six-input lookup table circuit with a redundant-magnetic tunnel junction-based active load for smart Internet-of-things applications

A variation-resilient single-ended six-input lookup table circuit, which makes it possible to implement any arbitrary six-input logic gates, is proposed. Since operating point is optimally tuned by the redundant magnetic tunnel junction devices after chip fabrication, adequate p-channel metal-oxide semiconductor (PMOS) feedback can be performed, which results in variation-resilient, energy-efficient operation. In fact, the energy consumption of the proposed circuit is 66% smaller than that of the conventional single-ended circuit.
