The input pads are connected to a memory controller or other ASIC over signal lines that include a diode located between the input pad and the ASIC and a resistance located between the input pad and the diode. The resistance and diode are selected such that an ESD event at an input pad triggers a discharge across the spark gap before it is transmitted on to the ASIC, while also allowing a high data rate for signals along the signal line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spark gap electrostatic discharge (ESD) protection for memory cards","description":"To protect memory cards, such as SD type cards, and similar devices from Electrostatic Discharge (ESD), the input pads of the device include points along their edges that are aligned with correspond p","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11477881","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.
