Abstract
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.
