Abstract
A device and related method, the device including memory and processing circuitry. The memory includes sets of source memory bands and a defragmentation destination memory band. Each set of source memory bands includes source memory bands and at least one portion of each source memory band stores valid data. The processing circuitry determines a merit score corresponding to each source memory band based on one or more characteristics of portions of data of each corresponding source memory band and determines, for each set of source memory bands, a respective source memory band that corresponds to a second-highest merit score. The processing circuitry identifies a set of source memory bands that includes a source memory band corresponding to a highest second-highest merit score and stores at least one portion of valid data from the source memory bands of the identified set of source memory bands to the defragmentation destination memory band.
