Abstract: A system includes a memory device having a plurality of groups of memory cells and a processing device communicatively coupled to the memory device.

Abstract: A variety of applications can include multiple memory die packages configured to engage in peak power management (PPM) across the multiple packages of memory dies. A communication line coupled to each memory die in the multiple memory die packages can be used to facilitate the PPM. A global management die can start a communication sequence among the multiple memory die packages to share a current budget across the multiple memory die packages by driving a signal on the communication line.

Abstract: Methods, systems, and devices for power architecture for non-volatile memory are described. A memory device may be configured to operate in a first mode and a second mode (e.g., a low power mode). When operating in the first mode, a voltage may be supplied from a power source (e.g., a power management integrated circuit) to a memory array and one or more associated components via a regulator. When the memory device transitions to operate in the second mode, some of the components supplied from the power source may be powered by a charge pump. Control information associated with the memory array may be stored to the one or more components (e.g., to a cache) that are powered by a charge pump.
