A Memristor-Based Logic NOT Circuit

Abstract

The invention discloses a logic inverter circuit based on memory resistors. The logic inverter circuit based on the memory resistors comprises a sixth memory resistor, a seventh memory resistor, a three state gate and a third resistor, wherein an input end of the sixth memory resistor is used as an input end of the logic inverter circuit, an input end of the seventh memory resistor is connected with supply voltage, a control end of the three state gate is connected with an output end of the sixth memory resistor, an input end of the three state gate is connected with an output end of the seventh memory resistor, an output end of the three state gate is grounded through the third resistor, and the output end of the seventh memory resistor is used as an output end of the logic inverter circuit. The logic inverter circuit based on the memory resistors can achieve a logical processing function of an existing gate circuit, improves reliability and flexibility of an electronic device, and simultaneously reduces cost, is superior to a traditional logic gate circuit based on COMS in the aspects of integration degrees, power dissipation, speed and the like, achieves unification of storage and processing of information, and facilitates overcoming of bottleneck problems caused by separation of the processing and the storage of the information in an existing computer system structure.

Description

technical field [0001] The invention belongs to the technical field of digital circuits, and more specifically relates to a logic NOT gate circuit based on a memristor. Background technique [0002] From the day the computer was invented, scientists and technologists have dreamed of a day when computers could work like the human brain. Since the world's first memristor was developed by Hewlett-Packard Labs in the United States in April 2008, which confirmed the existence of the "fourth electronic component" memristor, memristors can provide outstanding memory and logic functions through simple packaging. The performance has attracted the attention of scientists, and using it to simulate brain neuron synapses has become the goal of many scientists. In 2009, a research team at the University of Michigan in the United States produced a memristor circuit that simulates brain synapses, which confirmed the previous assumption that memristors can be used in the production of compu...
