In one aspect, a time parameter (e.g., dwell time) and/or heuristics (e.g., error count, error rate, number of reads, number of times programmed, etc.) are used in a garbage collection scheme. For example, in some implementations, the method of garbage collection for a storage medium in a storage system includes (1) determining a time parameter for a block in the storage medium, and (2) in accordance with a determination that the time parameter for the block is greater than a first threshold time, enabling garbage collection of the block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Heuristic aware garbage collection scheme in storage systems","description":"The various implementations described herein include systems, methods and/or devices used to enable heuristic aware garbage collection in storage systems (e.g., non-volatile data storage systems using","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9639463","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.
