Methods, systems, and devices for data transfer for wear-leveling are described. Data may be stored in pages of banks and the banks may be grouped into bank clusters. A host device may address one bank of a bank cluster at a time. Data may be transferred from a bank to a buffer or a different bank cluster for wear-leveling purposes and this data transfer may take place opportunistically while a second bank, which may be in the same bank cluster, is being accessed based on an access command.
