Programmer's data that is transferred from a programming device to a storage device is initially stored in a memory device of the storage device by using a durable data-retention storage setup. After the storage device is embedded in a host device, 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. 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 of the memory device as conventional SBC cells or as unconventional MBC cells. After the storage device is embedded in a host device, the programmer's data, or selected parts thereof, is read from the memory device and rewritten into it by operating selected memory cells of the memory device as conventional MBC cells.
A storage device comprising:
The storage device of claim 11, wherein the memory includes multi-bit cells and wherein the first storage mode includes storing the data into the multi-bit cells based on a first voltage threshold, the first voltage threshold determining a first set of voltage values for bits stored in the multi-bit cells, and the second storage mode includes storing the data into the multi-bit cells based on a second voltage threshold, the second voltage threshold determining a second set of voltage values for bits stored in the multi-bit cells.
A method comprising:
A storage device comprising:
