Classification: CPC G  Y | IPC G

Claim 19:
20. A non-transitory computer-readable medium storing instructions that when executed by a memory controller of a memory system cause the memory controller to perform a method of managing power of the memory system, wherein the memory system comprises at least one memory devices each of which comprises an array of memory cells powered by a first power source, the memory system further comprises a memory controller coupled to the at least one memory device and powered by a second power source, and the method comprises:
separating memory operations based on whether the memory operations cause power consumption from the first power source or the second power source, respectively, if executed, into at least a first queue and a second queue;
maintaining the first queue with memory operations that cause power consumption from a first one of the first and second power sources if executed;
determining a current power consumption value of the first one of the first and second power sources indicating total concurrent power consumption of executing a plurality of memory operations in parallel;
determining an add-on power consumption value indicating additional power consumption of executing a first subsequent memory operation in the firstqueue;
determining whether a summation of the current and the add-on power consumption values exceeds a first predetermined power consumption threshold associated with the first one of the first and second power sources; and
responsive to determining that the summation of the current and the add -on power consumption values does not exceed the first predetermined power consumption threshold, releasing the first subsequent memory operation from the first queue to execute the first subsequent memory operation in parallel with the plurality of memory operations.
