Abstract:
Methods, systems, and devices for deck-level shunting in a memory device are described. A memory device may include memory arrays arranged in a stack of decks over a substrate, and a combination of deck selection circuitry and shunting circuitry may be distributed among the decks to leverage common substrate-based circuitry, such as logic or addressing circuitry. For example, each memory array of a stack may include a set of digit lines and deck selection circuitry, such as deck selection transistors or other switching circuitry, operable to couple the set of digit lines with a column decoder that may be shared among multiple decks. Each memory array of a stack also may include shunting circuitry, such as shunting transistors or other switching circuitry operable to couple the set of digit lines with a plate node, thereby equalizing a voltage across the memory cells of the respective memory array.
