Method of operation of encoding and decoding circuits based on memristor immaterial implication logic

Abstract

The invention discloses a coding and decoding cross-array circuit based on memristive immaterial implication. The circuit combines immaterial implication 'not-and' type features with a coding and decoding logic expression, through several steps of immaterial implication operations, a coding or decoding result can be detected on an output unit. The coding and decoding cross-array circuit based on the memristive immaterial implication has the advantages that a pure memristive implement mode is adopted, an MOS tube is not used any more, the circuit has a simpler overall structure, lower power consumption and smaller size; a memristor has good non-volatility, can combine storage and operation, and it is expected to break through the bottleneck of a conventional John Von Neumann system framework; since the immaterial implication can be cascaded, a coding and decoding logic function can be extended into a cross array, thereby making the large-scale coding and decoding operation possible, theoperation efficiency in an actual production process is greatly improved, the operation flexibility is improved, and the size of a required chip is much smaller compared with that of a traditional structure.

Description

technical field [0001] The invention belongs to the field of cross arrays based on combinational logic circuits, and more specifically relates to an operation method of encoding and decoding circuits based on memristor immaterial implication logic. Background technique [0002] With the advent of artificial intelligence and brain-like era, large-scale fast computing has become hot, but this has brought challenges to traditional transistor devices and their logic circuits. It can be seen from Moore's law that with the development of integrated circuit technology, the number of electronic components on it will increase exponentially, and the size of transistor devices will become smaller and smaller. However, factors such as current production technology, manufacturing costs, and social needs have led to the final It is becoming more and more difficult to improve the performance of integrated circuits. When the size of the transistor is close to the nanometer level, problems ...
