Memristor circuit for artificial synaptic weighting of pulse inputs

This paper presents a memristor based new synaptic circuit, consisting of five memristor in a bridge structure together with one differential amplifier. The circuit is able to perform positive and negative weighting for pulse type inputs in neural cells. Processing is conducted with applied pulses at a common terminal in different time slots. It is compact, non-volatile and low power efficient. Simulations of sign setting, weight setting and synaptic multiplication are performed with hp TiO2 memristor models.
