A user device includes a storage device including a flash memory; and a host connected to the storage device via an interface and adapted to transmit data to the storage device. The host provides the storage device with erase count information of the flash memory using a host flash translation layer (FTL), provides the storage device with reprogram information when the flash memory uses a reprogram method, or provides the storage device with page offset information of an open block of the flash memory.
