    Abstract: A memory controller with improved user fairness, a storage device including the memory controller, and an operating method of the memory controller are provided. A memory controller includes a command-unit workload calculator configured to calculate a workload by a unit of each command, based on resource consumption of a memory device, which is determined by performing at least one memory operation included in each of the commands, a user-unit workload calculator configured to calculate a workload caused by each of a plurality of users, based on the workload calculated by the unit of the command, and a command fetch unit configured to preferentially fetch, from a host, a command issued by a user who has caused a relatively small workload, based on calculation results of workloads of the plurality of users.
