Abstract: A storage device and an operating method thereof are provided. The storage device includes a non-volatile memory, an interconnect, a device controller and a buffer memory. The interconnect exchanges data with a host, receives a logging target setting request and a logging period setting request with respect to debugging information from the host, receives a debugging information logging request from the host, and receive a read request from the host. The device controller includes a buffer memory and controls the non-volatile memory, controls a logging operation on the debugging information based on a logging target and a logging period, which are requested by the host, in response to the debugging information logging request, and transmits the debugging information to the host in response to the read request. The device controller is further configured to logs the debugging information in the buffer memory according to the debugging information logging request.

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.
