  • Patent number: 11977748
    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.

  • Patent number: 11775185
    Abstract: A memory device includes a plurality of memory dies, each memory die of the plurality of memory dies comprising a memory array and control logic. The control logic comprises a plurality of processing threads to execute memory access operations on the memory array concurrently, a thread selection component to identify one or more processing threads of the plurality of processing threads for a power management cycle of the associated memory die and a power management component to determine an amount of power associated with the one or more processing threads and request the amount of power during the power management cycle.

  • Publication number: 20230195312
    Abstract: A memory device includes memory dies, each memory die including a memory array and control logic, operatively coupled with the memory array, to perform peak power management (PPM) operations. The PPM operations include causing a memory die to be placed in a suspended state to suspend execution of a first media access operation with a reserved current budget, receiving a set of requests to execute at least a second media access operation during the suspended state, and in response receiving the set of requests, handling the set of requests by implementing current budget arbitration logic with respect to the reserved current budget.
