The input circuit of the semiconductor apparatus may include a switching unit configured to transfer the signal inputted through the test input terminal to the second input buffer according to a test mode signal. The input circuit of the semiconductor apparatus may include a comparison unit configured to compare the first input signal with the second input signal and to generate a comparison signal, and a storage unit configured to store the comparison signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Input circuit of three-dimensional semiconductor apparatus capable of enabling testing and direct access","description":"An input circuit of a semiconductor apparatus may include a first input buffer configured to receive a signal through a test input terminal and to output a first input signal, a second input buffer co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9589670","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.
