SYSTEM AND METHOD OF UPDATING METABLOCKS

摘要

A method includes, in a data storage device that includes a non-volatile memory having multiple memory dies, determining whether one or more metablocks are metablock update candidates based on relinking metrics corresponding to the one or more metablocks. Each memory die of the multiple memory dies includes multiple blocks of storage elements and metablocks are formed through linking of blocks from the multiple memory dies. The method also includes comparing a number of the metablock update candidates to a relinking pool threshold. The method further includes, in response to the number of the metablock update candidates satisfying the relinking pool threshold, updating the linking of the blocks of the metablock update candidates to form updated metablocks.
