A memory device and a method for rescheduling memory operations is disclosed. The method includes receiving memory operations for memory arrays of a memory device; storing the memory operations in queues associated with the memory array; estimating power consumption for each of the memory operations queued in the queues based on a power model; determining that a memory operation causes an estimated power consumption of the memory device to be exceeded over an allowable power budget within a first time window; determining a candidate memory operation in the queues that is scheduled to operate in a second time window after the first time window, wherein the candidate memory operation has less power consumption than the memory operation according to the power model; and dynamically reordering the memory operations in the queues and generating rescheduled memory operations by reordering the memory operation out of the first time window and reordering the candidate memory operation into the first time window.
