Abstract
A storage device, and a method of operating the storage device, includes a plurality of memory devices configured to store peak power information including information about a plurality of peak power periods and information about IDs respectively corresponding to the plurality of peak power periods. The storage device also includes a memory controller configured to assign an ID to each of the plurality of memory devices and control the memory devices so that one or more memory devices having an identical ID corresponding to a target period, among the plurality of peak power periods, perform a memory operation at peak power.
Claims18
A storage device, comprising:
- a plurality of memory devices configured to store peak power information including information about a plurality of peak power periods and information about identifications (IDs) respectively corresponding to the plurality of peak power periods;
- and
- a memory controller configured to assign an ID to each of the plurality of memory devices and control the memory devices so that one or more memory devices having an identical ID corresponding to a target period, among the plurality of peak power periods, perform a memory operation at peak power.
A memory device, comprising:
- a plurality of memory cells;
- a peripheral circuit configured to perform a memory operation on the plurality of memory cells;
- a power management information storage configured to store peak power information including information about a plurality of peak power periods and information about identifications (IDs) respectively corresponding to the plurality of peak power periods;
- and
- an operation processor configured to control the peripheral circuit so that the memory operation is performed at peak power during a target period corresponding to an ID assigned to the memory device, among the plurality of peak power periods.
A method of operating a memory device, comprising:
- receiving, from a memory controller, a peak power setting command for setting peak power information, wherein the peak power information includes information about a plurality of peak power periods and information about identifications (IDs) respectively corresponding to the plurality of peak power periods;
- storing the peak power information;
- storing the ID information in response to an ID assignment command received from the memory controller;
- receiving a memory operation command from the memory controller;
- and
- performing a memory operation at the peak power during a target period corresponding to an assigned ID indicated by the ID information, among the plurality of peak power periods, in response to the memory operation command.
