The transistor also includes first and second ends of the ferroelectric layer which are proximal correspondingly to the source and drain regions. The ferroelectric layer includes dipoles. A first set of dipoles at the first end of the ferroelectric layer has a first polarization. A second set of dipoles at the second end of the ferroelectric layer has a second polarization, the second polarization being substantially opposite of the first polarization."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-bit memory storage device and method of operating same","description":"A ferroelectric field-effect transistor (FeFET) configured as a multi-bit storage device, the FeFET including: a semiconductor substrate that has a source region in the semiconductor substrate, and a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11532746","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.
