Abstract

A method includes determining a first logical block address (LBA) range of a first set of data units of a first candidate block of the memory. The method also includes determining a second LBA range of a second set of data units of a relocation block of the memory. The method also includes determining that the first LBA range matches the second LBA range. The method further includes relocating first valid data of the first candidate block to the relocation block of the memory in response to determining that the first LBA range matches the second LBA range, where the first LBA range corresponds to multiple LBAs.
