1. A memory device comprising:
a plurality of memory dies, each memory die of the plurality of memory dies comprising;
a memory array; and
control logic, operatively coupled with the memory array, to perform operations comprising:
receiving a request to perform a memory access operation, wherein the memory access operation comprises a set of sub-operations;
selecting a current quantization data structure from a plurality of current quantization data structures, wherein each current quantization data structure of the plurality of current quantization data structures maintains, for each sub-operation of the set of sub-operations, a respective current quantization value reflecting an amount of current that is consumed by the sub-operation based on a set of peak power management (PPM) operation parameters; and
causing the memory access operation to be performed using PPM based on the current quantization data structure.
