    Abstract: A storage device including a memory controller and an operating method of the memory controller are provided. The storage device includes a non-volatile memory device including a write buffer configured to store write data provided from a host and a journal buffer configured to store a journal log, a volatile memory device configured to temporarily store metadata, and a memory controller configured to provide the non-volatile memory device with a journaling command, that includes the journal log and the physical address corresponding to the journal buffer, and which issues a command to store the journal log in the journal buffer, to update the metadata temporarily stored in the volatile memory device, and to control the volatile memory device to store updated metadata to the non-volatile memory device.
