A method may include sending a command with bitmaps from a processor to a non-volatile storage device interface controller to perform a read operation on multiple blocks across multiple planes. The bitmaps may indicate positions of valid data units in respective pages within the blocks. The method may further include issuing an initial batch of multi-plane read commands to read a page of data from each of the plurality of planes into cache registers, obtaining specified column addresses to selectively identify valid data units for transferring based on the bitmaps and a data unit size, issuing subsequent batches of multi-plane cache read commands followed by data transfer commands, and issuing a cache read end command followed by a last set of data transfer commands. The data transfer commands may include the specified column addresses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Valid data retrieval for garbage collection","description":"Systems and methods are provided for data retrieval in garbage collection (GC) processes.
