Abstract:
A method, according to one embodiment, includes: receiving a recirculation command, performing a coarse page lookup to determine valid ones of logical pages to be recirculated, issuing write commands for the valid logical pages, requesting performance of a fine page lookup on source physical addresses containing the valid logical pages to verify the valid logical pages, receiving verified valid logical pages resulting from the fine page lookup, and sending the write commands corresponding to the verified valid logical pages. Other systems, methods, and computer program products are described in additional embodiments.
