A method of operating an electronic device which includes a host device and a storage device. The method includes initiating a first write operation of target data and a first logical block address (LBA), generating target identification information of the target data in response to initiating the first write operation, determining that the target identification information is registered at a mapping table of the host device, determining that the first LBA is different from a previous LBA corresponding to the target identification information in the mapping table, updating the mapping table such that the previous LBA is changed to the first LBA, providing the storage device with a first request for inheritance of previous lifetime information, and storing, in a history table of the storage device and based on the first request, first lifetime information that inherits the previous lifetime information.

Electronic devices inheriting lifetime information, and methods of operating the same

A storage device includes a non-volatile memory; a volatile memory; and a storage controller configured to: receive a new data and append data write command from a host, write new data and append data to at least one of the non-volatile memory and the volatile memory, receive, from the host, a remap command including mapping information between old data and the new data and a first identification (ID), based on the remap command, store in the volatile memory the mapping information between the old data and the new data and the first ID, receive, from the host, a metadata write command requesting writing meta data for the append data and including the first ID, and based on the metadata write command, update the mapping information between the old data and the new data, and write metadata related to the append data to the non-volatile memory.

Storage device performing atomic write, host controlling storage device, and operating method of storage device

A method of operating a host device includes monitoring execution of a command sequence corresponding to a specific situation, determining whether working file set information for the command sequence is present in a database, transferring a logical address corresponding to the working file set information to a device driver driving a storage device when the working file set information is present in the database, requesting map information corresponding to the logical address from the storage device, receiving the map information from the storage device, and storing the map information in a buffer memory.

Methods of operating host device and storage device, and electronic device

Provided is a through-focus image-based metrology device including an optical device, and a computing device configured to acquire at least one through-focus image of a target from the optical device, generate an intensity profile based on the acquired at least one through-focus image, and perform metrology on the target based on the generated intensity profile, wherein the optical device includes a stage on which the target is disposed, the stage being configured to move by one step in at least one direction based on control of the computing device, and to acquire the at least one through-focus image, an image sensor disposed on the stage, an objective lens disposed between the image sensor and the stage, the objective lens being configured to transmit reflected light from the target, and a light source configured to emit illumination light to the target through the objective lens.
