Abstract: 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.

Abstract: 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.
