The equilibrium point stability is analyzed to reveal the Neimark\u2013Sacker bifurcation behaviors, clarifying the intricate dynamics of the proposed network. Dynamical characteristics, including periodic, quasi-periodic, chaotic, and hyperchaotic states, are systematically explored using phase diagrams, iterative series, Lyapunov exponent spectra, and bifurcation diagrams. Furthermore, symmetry-induced dynamical phenomena under symmetric initial conditions are observed, demonstrating the coexistence of stable points and chaotic attractors. Compared with traditional tri-cycle resistive synapse HNN models, the proposed TCMS-HNN significantly enhances dynamic complexity and computational efficiency. Finally, the DSP implementation is completed, realizing the digital circuit of the TCMS-HNN model. These results provide important theoretical insights for neuroscience research and complex dynamical systems, also highlight its substantial potential in neuromorphic computing and secure information encryption.<\/jats:p>","DOI":"10.1142\/s0218127426500197","type":"journal-article","created":{"date-parts":[[2025,10,31]],"date-time":"2025-10-31T10:11:16Z","timestamp":1761905476000},"source":"Crossref","is-referenced-by-count":5,"title":["Discrete Tri-Cycle Memristive Synapse Hopfield Neural Network: Dynamics and Implementations"],"prefix":"10.1142","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-1081-8953","authenticated-orcid":false,"given":"Yueqi","family":"Song","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Dalian Polytechnic University, Dalian 116034, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5790-7429","authenticated-orcid":false,"given":"Suo","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Dalian Polytechnic University, Dalian 116034, P.\u00a0R.\u00a0China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5136-0469","authenticated-orcid":false,"given":"Xian-Ying","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Dalian Polytechnic University, Dalian 116034, P.\u00a0R.\u00a0China"}]}],"member":"219","published-online":{"date-parts":[[2025,10,31]]},"reference":[{"key":"S0218127426500197BIB001","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-024-46976-4"},{"key":"S0218127426500197BIB002","doi-asserted-by":"crossref","unstructured":"Bao, H., Ren, P., Xu, K., Yang, L., Zhou, H., Li, J., Li, Y. & Miao, X.
