For example, thespecification for Secure Digital (SD) cards requires reserved areas to supportspecial copy protection and security features.ġ. Where applicable, reservingsome cells for special features.Reserving some cells foruse by the flash storage device’s controller, e.g., for storing firmwareupdates and other controller-specific information.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. To enable flash storage devices to store and access customer files conveniently, a file management system must be created to allow any device or computer to identify the files stored in the flash storage device. Creating a File AllocationTable (FAT) or other directory.Therefore, some cells are held in reserve to replace any memory cells that may fail over time. Reserving some cells to serve as 'spares.' Flash memory cells have a long but finite lifetime.Identifying all defectivecells and taking steps to ensure that no data will be written to or read from adefective cell.Testing each memory cell inthe flash storage device.These steps, loosely called 'formatting', use some of the memory cells within the device and thus reduce the capacity available for data storage by the end user.įormatting includes the followingoperations: When a flash storage device is manufactured, steps are taken to ensure that the device operates reliably and permits the host device (computer, digital camera, PDA, etc.) to access the memory cells i.e., to store and retrieve data on the flash storage device. Therefore, you will not see the full capacity. Some of the flash storagedevice’s listed capacity is used for formatting and other functions and is notavailable for data storage.
