    Abstract: First firmware metadata and second firmware metadata are based on nonvolatile metadata stored in the nonvolatile memory device. A normal operation including a first management operation resulting in a change of the first firmware metadata and an access operation in which the nonvolatile memory device is accessed may be performed. A virtual operation is performed including a second management operation resulting in a change of the second firmware metadata and in which the access operation is not performed. Whether an error has occurred in the first firmware metadata is determined by comparing the change of the first firmware metadata resulting from the first management operation and the change of the second firmware metadata resulting from the second management operation. An error in the metadata may be monitored through the redundant performance of the management operation that results in the change of the metadata without a corresponding access to the nonvolatile memory device.

    Abstract: A storage device includes; a nonvolatile storage including a first region and a second region, a storage controller controlling operation of the nonvolatile storage, and a buffer memory connected to the storage controller. The storage controller stores user data received from a host device in the second region, stores metadata associated with management of the user data and generated by a file system of the host device in the first region, loads the metadata from the first region to the buffer memory in response to address information for an index node (inode) associated with the metadata, and accesses the target data in the second region using the metadata loaded to the buffer memory.

    Abstract: An electronic device includes a plurality of cameras, a memory, and at least one processor. The at least one processor is configured to identify a change in a distance between a focused subject and the electronic device within a first frame through at least some of the plurality of cameras while a video with a bokeh effect is acquired. The at least one processor is also configured to provide the bokeh effect of the video within a first background area in a second frame in response to identifying that a difference between a first distance and a second distance is within a criterion range. The at least one processor is further configured to provide the bokeh effect of the video within a second background area identified based on a third distance in the second frame in response to identifying that the difference is out of the criterion range.
