  • Publication number: 20240020018
    Abstract: Methods, apparatuses and systems related to managing deck-specific read levels are described. The apparatus may include a memory array having the memory cells organized into two or more decks. The apparatus can determine a delay between programming the decks. The apparatus can derive and implement the deck-specific read levels by selectively adjusting a base read level with an offset level according to the delay and/or the targeted read location.
