Deck offset techniques for multi-deck non-volatile memory can reduce the average raw bit error rate (RBER) for a memory system. Deck offset can enable accessing different physical decks for the same input deck address. In one example in a system with multiple memory components, different physical decks are accessed across multiple memory components for the same logical deck address. In one example in a system with one memory component, different physical decks are accessed across multiple partitions of the same memory component.
