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. Local management dies can use the received signal having clock pulses driven by the global management die on the communication line to engage in the PPM. To engage in global PPM, each memory die can be structured, to be selected as the global management die or a local management die, with one or more controllers to interface with the multiple memory die packages and to handle current budget limits.
