    Abstract: Methods, systems, and devices for cell voltage accumulation discharge are described. One or more sections of a bank of ferroelectric memory cells may be coupled with one or more access lines. By activating one or more switching components, one or more sections (that may include a memory array and/or a driver) of memory cells may be isolated. When isolated, a voltage may be applied across an access line associated with the section to activate an access device of each memory cell. By activating a switching component of a respective memory cell, a capacitor of the memory cell may be discharged and then the isolated section may be coupled with the plurality of access lines.

    Abstract: Methods and devices for reading a memory cell using multi-stage memory sensing are described. The memory cell may be coupled to a digit line after the digit line during a read operation. A transistor may be activated to couple an amplifier capacitor with the digit line during the read operation. The transistor may be deactivated for a portion of the read operation to isolate the amplifier capacitor from the digit line while the memory cell is coupled to the digit line. The transistor may be reactivated to recouple the amplifier capacitor to the digit line to help determine the value of the memory cell.

    Abstract: Apparatuses for supplying power supply voltage in a plurality of dies are described. An example apparatus includes: a circuit board; a regulator on the circuit board that regulates a first voltage; a semiconductor device on the circuit board that receives the first voltage through a power line in the circuit board. The semiconductor device includes: a substrate on the circuit board, stacked via conductive balls, that receives the first voltage from the power line via the conductive balls; a plurality of dies on the semiconductor device, stacked via bumps, each die including a first conductive via that receives the first voltage via the bumps; a plurality of pillars between adjacent dies and couple the first conductive vias of the adjacent dies; and a sense node switch circuit that selectively couples one first conductive via of one die among the plurality of dies to the regulator.
