A high-speed and low-power pre-read and write sense amplifier (PWSA) provide VCMA effect precessional switching of MTJ cells which include pre-read and comparison steps which reduce power consumption. An embodiment of the PWSA circuit is described with write and pre-charge circuit, S and D latches, comparison circuit, and a differential amplifier and control circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fast and low-power sense amplifier and writing circuit for high-speed MRAM","description":"A fast and low-power sense amplifier and writing circuit for high-speed Magnetic RAM (MRAM) which provides the long retention times and endurance of magnetic tunnel junction (MTJ) cells, while providi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9672886","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.
