The reference signal is selected depending on whether to compensate an operating margin fluctuating according to the word-line activation time (or word-line pulse width), or to compensate an operating margin fluctuating according to the process fluctuation (or variation in threshold voltage). By controlling the back-gate biases according to the word-line pulse width, an operating margin fluctuating according to the word-line pulse width, and an operating margin fluctuating owing to the variation in threshold voltage during its fabrication are improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"The semiconductor device makes a comparison between a word-line timing signal for determining a word-line activation time and a reference signal, applies a back-gate bias for enlarging a read margin w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493775","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.
