When a pre-stored voltage/temperature condition occurs again, ZQ calibration is not performed. Instead, the associated pre-stored calibration code is retrieved from the register array and provided to the IO circuit. When a voltage/temperature condition of the semiconductor device does not match any pre-stored voltage/temperature condition in the register array, a ZQ calibration is performed. When the ZQ calibration is performed, a register in the register array is selected according to an update policy and updated by the calibration code newly provided by the ZQ calibration along with the voltage/temperature condition at the time when the ZQ calibration is performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatuses and methods for ZQ calibration","description":"In an example semiconductor device, the voltage/temperature conditions of the semiconductor device and associated calibration codes of multiple instances of ZQ calibrations are pre-stored in a registe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11237579","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.
