Abstract
A method of managing wear leveling in a data storage device includes determining whether a reliability measurement associated with a first portion of a first nonvolatile memory die satisfies a threshold. The first nonvolatile memory die is included in a plurality of memory dies. The method includes, in response to determining that the reliability measurement associated with the first portion of the first nonvolatile memory die satisfies the threshold, transferring first data from the first portion of the first nonvolatile memory die to a second nonvolatile memory die of the plurality of memory dies.
