The charging pulse of opposite polarity may comprise equal or different width and amplitude than that of the write pulse, may be applied with each write pulse or a series of write pulses, and may be applied prior to or subsequent to the write pulse. A register is also used to keep track of the read pulse polarity such that read pulses of alternating polarity can be used in reading operations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of writing to a spin torque magnetic random access memory","description":"Circuitry and methods provide an increased tunnel barrier endurance (lifetime) previously shortened by dielectric breakdown by providing a charging pulses of opposite polarity in comparison with write","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9589622","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.
