Abstract: Provided are a memory controller controlling power consumption, a memory system including the memory controller, and a method of operating the memory controller. The memory controller includes a write amplification factor (WAF) calculator configured to calculate a WAF value relating to a ratio of an amount of data written to the memory device to an amount of write data provided from the host, a performance controller configured to adjust performance of the write operation such that the performance of the write operation decreases, compared to a certain reference performance value, as the calculated WAF value increases, the performance controller configured to thereby control the memory device to consume power within a power range, and a command processor configured to control execution of write commands for performing the write operation, based on control by the performance controller.
