Abstract
Systems, methods and/or devices are used to pair metablocks in a non-volatile storage device. In one aspect, a method of data organization of a memory device includes, writing data to and reading data from respective metablocks in a set of metablocks. The method further includes while performing said writing and reading: (1) accessing one or more management data structures in controller memory, identifying two or more metablock pairs; (2) accessing and updating metablock status information indicating which metablocks of the set of metablocks are closed, free and open; and (3) accessing and updating a valid count, corresponding to a number of sub-block memory units having valid data for each of a plurality of metablocks in the set of metablocks.
