    Abstract: A memory cell may include a capacitor and a switch. Accessing the memory cell in a memory array of a memory device may include applying a word line voltage to the switch to electrically couple the capacitor to a data line. However, if not compensated for, applying the word line voltage may induce undesired voltages on adjacent memory cells of the memory arrays. Systems and methods are described to reduce an effect of one or more parasitic capacitors causing the undesired voltage disturbance. For example, the memory array may provide compensatory voltages to adjacent word lines of a target word line to compensate for such undesired parasitic capacitors. Accordingly, an undesired voltage disturbance of the memory cells may be reduced.

    Abstract: A variety of applications can include apparatus having a memory device comprising plate select lines coupled to capacitors of memory cells of the memory device, plate line drivers coupled to the plate select lines, and a bias device coupled to each plate line driver. Use of a single bias device can allow for generation of robust current across multiple plate line drivers. The plate line drivers can be arranged with different formats that can operate with a single bias device. Plate select lines and the plate line driver can be structured in a scheme to balance the number of plate select lines and device counts for the plate line drivers.

    Abstract: A memory device may include various circuitry including multiple memory banks and a circuit under array. The circuit under array may include a number of control blocks each coupling to a respective memory bank. The control blocks may route data and commands to the memory cells of the memory arrays of the respective memory banks. In particular, the control blocks may include routing circuitry including column routing circuits, row routing circuits, and coupling routing circuits to route data between external devices and the memory banks. For example, the coupling routing circuits may couple the column routing circuits and the row routing circuits. Implementing the coupling routing circuits with the control blocks may reduce a footprint of the circuit under array.
