    Abstract: Provided is an operating method of a storage controller that includes a buffer memory, an address manager, and a direct memory access (DMA) engine and controls a non-volatile memory device. The operating method includes receiving, from an external host device, a read request including a host address, storing, by an address manager in response to the read request, mapping information about the host address and a command identifier corresponding to the read request in a translation table, setting, by the DMA engine, a destination address of read data corresponding to the read request to a virtual address corresponding to the command identifier, and transmitting the read data to the virtual address, and translating, by the address manager based on the translation table, the destination address of the read data from the virtual address to the host address.
