COMMITTED TO MEMORY
3.Reserving some cells to serve as “spares.” Flash memory cells have a long but finite
lifetime. Therefore, some cells are held in reserve to replace any memory cells that
may fail over time.
4.Creating a File Allocation Table (FAT) or other directory. To enable flash storage
devices to conveniently store and access customer files, a file management system
must be created to allow any device or computer to identify the files stored in the
flash storage device. The most common type of file management system for flash
storage devices is the File Allocation Table (FAT), which is also used on hard drives.
5.Reserving some cells for use by the flash storage device’s controller, e.g., for storing
firmware updates and other controller-specific information.
6.Where applicable, reserving some cells for special features. For example, the
specification for Secure Digital (SD) cards requires reserved areas to support special
copy protection and security features.
