Class Information
Number: 365/222
Name: Static information storage and retrieval > Read/write circuit > Data refresh
Description: Subject matter wherein decaying information is read before it becomes unrecognizable, and rewritten in original form, e.g., charge on a capacitor is read before too much has leaked off, then rewritten to a fully charged state.
