A novel memristor bridge circuit which is able to perform zero, negative and positive synaptic weightings in neuron cells is proposed. It is composed of four memristors and three transistors for weighting operation and voltage-to-current conversion, respectively. It is compact as it can be fabricated in nano meter scale. It is power efficient since its operation is pulse-based. Its input terminals are utilized commonly for applying both weight programming and weight processing signals via time sharing. By programming on each memristor of the memristor bridge circuit, the signed weighting values can be set on the memristor bridge synapses. The features of proposed architecture are investigated via various simulations.
