Title: Preloading data into a flash storage device

Abstract: Programmer's data that is transferred from a programming device (160) to a storage device (100) is initially stored in a memory device (120) of the storage device (100) by using a durable data-retention storage setup (210). After the storage device is embedded in a host device (170), the programmer's data is internally (i.e., in the storage device) read from the memory device and rewritten into the memory device by using a conventional storage setup (220). Using a durable data-retention storage setup may include temporarily (i.e., before the storage device is embedded in a host) operating selected memory cells (124) of the memory device as conventional single-bit per cell (SBC) cells or as unconventional multi-bit per cell (MBC) cells. After the storage device (100) is embedded in a host device (170), the programmer's data, or selected parts thereof, is read from the memory device (120) and rewritten into it by operating selected memory cells (126, 128) of the memory device as conventional MBC cells.
