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: Disclosed is an electronic device which includes a host device and a storage device. A method of operating the electronic device includes performing, by the host device, a validity check operation of a target host zone among a plurality of host zones supporting a sequential write operation, generating, by the host device, block map information of the target host zone based on the validity check operation, the block map information including identification information of the target host zone and validity information of all data blocks in the target host zone, and sending, by the host device, the block map information to the storage device.
