Each CAM sub-bank further includes first-stage match lines (MLs), first-stage search line (SL) pairs, second-stage MLs, and second-stage SL pairs. Each second-stage SL pair is coupled to a column of CAM cells in the second stage and is gated by an SL enable (SL_EN signal). Each CAM sub-bank further includes a circuit operative to receive all of the first-stage MLs as input and de-assert the SL_EN signal when none of the first-stage MLs indicate a match. De-assertion of the SL_EN signal blocks a second portion search key from being provided to the second-stage SL pairs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamically gated search lines for low-power multi-stage content addressable memory","description":"A content addressable memory (CAM) device includes multiple CAM sub-banks Each CAM sub-bank includes an array of CAM cells arranged in rows and columns and partitioned into a first stage and a second ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11967377","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.
