[Abstract]:With the development of electronic technology and material technology, the mode of complex information processing is becoming more and more efficient and succinct. As the latest achievement of nanomaterials, the memristor connects magnetic flux and charge with memory characteristics, coupled with its natural nanoscale size, and has received great attention and research from the academic and industrial circles. The device can simulate the memory function of the synapse in the human brain, which is expected to completely change the working mode of the computer and the way of information processing. This paper analyzes the current research status of the memristor, and then summarizes the theory and Simulation of the mathematical model of the memristor. Then, the coupling behavior between the memristors is analyzed in detail, and the initial method is discussed. The influence of the resistance on the working range of the memristor. Finally, the correlation analysis and simulation experiment of the memristor bridge circuit are carried out, and the defects are improved. First, the mathematical model of the HP memristor, the spin memristor and the magnetic control coupled memristor is analyzed, and the theoretical analysis and simulation experiments are carried out. Secondly, in the magnetic control The mathematical model of the magnetron coupled memristor is built on the basis of the memristor, and the coupling behavior of the series and parallel of the memristor under different connection directions is summarized, and the relationship curve of the coupled memristor is displayed intuitively by the designed graphical user interface. Then, the change of the normal working range of the memristor under different initial recristors is discussed. Then, using the Pspice simulation circuit, the coupling behavior between the memristors is shown again from the direction of the circuit. Finally, the updating rules of the synaptic circuit weight of the memristor bridge are explained in detail, and the simulation experiment is carried out with the circuit simulation software. The memristor synaptic circuit saves the conversion process between current signals and voltage signals.
