The capping pattern includes a lower capping pattern, an upper capping pattern between the lower capping pattern and the top electrode, a first non-magnetic pattern between the lower capping pattern and the upper capping pattern, and a second non-magnetic pattern between the first non-magnetic pattern and the upper capping pattern. Each of the lower capping pattern and the upper capping pattern includes a non-magnetic metal. The first non-magnetic pattern and the second non-magnetic pattern include different metals from each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic memory device","description":"Disclosed is a magnetic memory device including a pinned magnetic pattern and a free magnetic pattern that are sequentially stacked on a substrate, a tunnel barrier pattern between the pinned magnetic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11942128","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.
