Storage device, memory controller and operating method of the memory controller

Abstract

An electronic device, and more particularly, a storage device for mitigating periods where a peak current occurs from currents overlapping is provided. The storage device includes a memory device including a plurality of dies and a memory controller controlling the memory device. The memory device generates status information about an amount of current consumed by each of the plurality of dies during a busy period when all of the plurality of dies are in a busy state, and wherein the memory controller determines, based on the status information, whether peak currents for multiple dies of the plurality of dies are consumed in a common sub-period of a plurality of sub-periods which span the busy period, and when it is determined that peak currents for multiple dies are consumed in the common sub-period, the memory controller controls the memory device to suspend an operation on a die among the plurality of dies.
