    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.

    Abstract: Methods, systems, and devices for power management for a memory device are described. An apparatus may include a memory die that includes a power management circuit. The power management circuit may provide a voltage for operating a set of memory dies of the apparatus based on a supply voltage received by the memory die. The voltage may be distributed to the set of memory dies in the apparatus.

    Abstract: A voltage of a conductive line, such as a control line, a data line, or a voltage supply line associated with a memory die may be monitored. A frequency response of the voltage may be analyzed to determine if the conductive line may be operating at or near a specific frequency, such as a resonance frequency. If the conductive line is operating at or near the specific frequency, an action, such as a memory operation, may be performed to mitigate the resonance of the conductive line. The monitoring, analyzing, and action performing may be accomplished with circuitry of the memory die.

    Abstract: Methods, systems, and devices for predictive power management are described. Correlations may be identified between a set of commands performed at the memory device and oscillating voltage patterns, or a resonance frequency, or both. Voltages may be monitored by the memory device and be compared to the identified voltage pattern to mitigate undesirable oscillating voltages and resonance frequency.

    Abstract: Methods, systems, and devices for memory device power management are described. An apparatus may include a memory die that includes a power management circuit. The power management circuit may provide a voltage for operating one or more memory dies of the apparatus based on a supply voltage received by the memory die. The second voltage may be distributed to the one or more other memory dies in the apparatus.

    Abstract: A memory device may include a pin for communicating feedback regarding a supply voltage to a power management component, such as a power management integrated circuit (PMIC). The memory device may bias the pin to a first voltage indicating that a supply voltage is within a target range. The memory device may subsequently determine that a supply voltage is outside the target range and transition the voltage at the pin from the first voltage to a second voltage indicating that the supply voltage is outside the target range. The memory device may select the second voltage based on whether the supply voltage is above or below the target range.

    Abstract: Methods, systems, and devices for feedback for power management of a memory die using shorting are described. A memory device may short a first rail with a voltage source for communicating feedback regarding a supply voltage to a power management component, such as a power management integrated circuit of a memory system. The memory device may detect a condition of one or more voltage rails for delivering power coupled with the array of memory cells. The memory device may short a first rail of the network of components for delivering power with a voltage source based on detecting the condition. In some cases, the memory device may generate a feedback signal across the first rail of the network of components for delivering power based on shorting the first rail.
