Abstract
Official abstract text for this publication.
A storage controller is configured to determine a reliability metric of a storage division of a solid-state storage medium based on one or more test read operations. The storage division may be retired based on the reliability metric and/or the age of the data on the storage division. A storage division comprising aged data may be marked for post-write reliability testing, which may comprise determining a post-write reliability metric in response to grooming and/or reprogramming the storage division. The storage controller may project the reliability metric of the storage division to the end of a predetermined data retention period. Portions of a storage divisions that exhibit poor reliability may be removed to improve the reliability of the storage division without taking the entire storage division out of service.
First claim
Opening claim text (preview).
We claim: 1. An apparatus, comprising: an age module configured to determine an age of data stored on a portion of a solid-state storage medium, wherein the age of the data corresponds to a time period that the data has been retained on the portion; and a reliability module configured to determine whether to retire the portion based on a comparison between the determined age of the data and a time threshold, wherein the reliability module is configured to determine whether to r…
