1. A computing system comprising:
a host;
a memory including a volatile memory and a memory controller; and
a storage device that is connected with the host through a first interface and that includes a nonvolatile memory and a storage controller, the storage device being configured to communicate with the host through a first port, to communicate with the memory through a second port, and to manage the memory,
wherein the memory is connected with the storage device through a second interface that is physically separated from the first interface,
wherein, in an initialization operation, the storage controller sends map data that is stored in the nonvolatile memory to the memory through the second interface, and
wherein, in the initialization operation, the memory controller stores the map data in the volatile memory.
