Abstract: A storage device including a nonvolatile memory device is provided. The storage device may include: a nonvolatile memory device; and a controller configured to control a read operation of the nonvolatile memory device according to a read request from an external host device. The controller is configured to read map data including a segment, and to store different types of map data in an internal random access memory (RAM) based on determining whether the segment corresponds to sequential data.
