    Abstract: A memory device includes memory dice, each memory die including: a memory array; a memory to store a data structure; and control logic that includes: multiple processing threads to execute memory access operations on the memory array concurrently; a priority ring counter, the data structure to store an association between a value of the priority ring counter and a subset of the multiple processing threads; a threads manager to increment the value of the priority ring counter before a power management cycle and to identify one or more prioritized processing threads corresponding to the subset of the multiple processing threads; and a peak power manager coupled with the threads manager and to prioritize allocation of power to the one or more prioritized processing threads during the power management cycle.

    Abstract: A method includes selecting a particular ready/busy pin (R/B #) among a plurality of R/B # pins that are associated with respective memory dice among a plurality of memory dice of a memory device. The method further includes receiving, by at least one memory dice among the plurality of memory dice, signaling indicative of performance of a memory access while the particular R/B # pin is set to low, and, initiating an internal clocking signal subsequent to receipt of the signaling indicative of performance of the memory access, wherein the internal clocking signal is associated with timing of operations performed by the plurality of memory dice.
