A host data router directs received data from a host to an appropriate predetermined portion based on a determined data type. A maintenance data router, based on predetermined minimum capacity overprovisioning targets for each predetermined portion, operates to adjust an amount of overprovisioning of physical capacity among the plurality of predetermined portions to reduce write amplification and increase performance in predetermined portions having data with a higher probability of host update. The method may include selecting a particular predetermined portion and a particular block within the selected predetermined portion on which to perform a maintenance operation to achieve the desired capacity overprovisioning."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for managing data in a memory device","description":"A non-volatile memory system may have a group of non-volatile memory cells having a plurality of predetermined portions, where each predetermined portion is associated with an open host write block of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9690491","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.
