Description

technical field [0001] The invention relates to the technical field of molecular circuits, in particular to a four-input factorial addition molecular circuit design method based on DNA chain replacement. Background technique [0002] The rapid development and constant updating of electronic computers make computers face the problem of miniaturization. With the development of large-scale integrated circuits, microelectronic devices based on silicon-based materials will have higher and higher requirements for integration. Therefore, ultra-large-scale and ultra-large-scale integrated circuits must face problems in both physical principles and traditional process technologies. This problem may be solved by developing a new manufacturing process or introducing new alternative manufacturing materials, but this requires higher costs and also increases the possibility of various uncertain errors. As a result, the advantages of the powerful parallel computing capability and high pr...
