A method of synchronizing time between a host device and a storage device is provided. The method includes: identifying, by the storage device, a time synchronization interval; notifying the time synchronization interval from the storage device to the host device; providing host time information from the host device to the storage device during the time synchronization interval; and synchronizing, by the storage device, time information of the storage device with the host time information.

A memory system includes a storage device including a nonvolatile memory device and a storage controller configured to control the nonvolatile memory device, and a host that accesses the storage device. The storage device transfers map data, in which a physical address of the nonvolatile memory device and a logical address provided from the host are mapped, to the host depending on a request of the host. The host stores and manages the transferred map data as map cache data. The map cache data are managed depending on a priority that is determined based on a corresponding area of the nonvolatile memory device.
