Abstract
A logical-to-physical (L2P) data structure and a physical-to-logical (P2L) data structure are maintained. The L2P data structure comprises table entries that map a logical address to a physical address. The P2L data structure comprises data entries that map a physical address to a logical address. The P2L data entries also comprise a data move status, a base address, and a boundary indicator. A move operation is detected, wherein the move operation indicates that data referenced by a logical address is to be moved from a source physical address to a destination physical address. Responsive to detecting the move operation, the data move status associated with the source physical address in the P2L data structure is updated.
