By using the 3D phase change memory to perform 3D convolution operation, the phase change units on the same bit line constitute a convolution kernel. Based on the multilayer stack structure, the upper and lower electrodes of the 3D phase change memory serve as the information input terminal, and they are convolved after passing through the respective phase change unit arrays, and the result of the convolution operation is superposed on the middle electrode in the form of current, thereby obtaining the sum of the convolution calculation results of the input information of the upper and lower electrodes, such that the 3D convolution operation is completed in one step."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-dimensional convolution operation device and method based on three-dimensional phase change memory","description":"The disclosure discloses a three-dimensional (3D) convolution operation device and method based on a 3D phase change memory, which includes a 3D phase change memory, an input control module, a setting","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11989644","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
