  • Patent number: 11778827
    Abstract: A microelectronic device comprises first digit lines, second digit lines, and multiplexer devices. The first digit lines are coupled to strings of memory cells. The second digit lines are coupled to additional strings of memory cells. The second digit lines are offset from the first digit lines in a first horizontal direction and are substantially aligned with the first digit lines in a second horizontal direction orthogonal to the first horizontal direction. The multiplexer devices are horizontally interposed between the first digit lines and the second digit lines in the first horizontal direction. The multiplexer devices are in electrical communication with the first digit lines, the second digit lines, and page buffer devices. Additional microelectronic devices, memory devices, and electronic systems are also described.

  • Publication number: 20220359554
    Abstract: Some embodiments include apparatuses and methods having a substrate, a memory cell string including a body, a select gate located in a level of the apparatus and along a portion of the body, and control gates located in other levels of the apparatus and along other respective portions of the body. At least one of such apparatuses includes a conductive connection coupling the select gate or one of the control gates to a component (e.g., transistor) in the substrate. The connection can include a portion going through a portion of at least one of the control gates.
