Each group contains a merged scan flip flop coupled to a series of scan flip flops. The merged scan flip flop in each of the groups is coupled to a respective read port of a memory unit, and a final scan flip flop in each of the groups is coupled to a respective write port of the memory unit. The system enables the memory unit to save the M bits of state data in N clock cycles. Each merged scan flip flop has a read select input that enables restoring of the state data into the M scan flip flops in N clock cycles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for retaining state data","description":"According to one embodiment, a system for retaining M bits of state data of an integrated circuit during power down includes M serially coupled scan flip flops divided into M/N groups, where the M sca","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462533","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.
