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.

Kingston’s Flash storage devices offer many advantages for both consumer and
industrial applications:

• Flash Storage Device Warranty: Kingston warrants that its Flash storage devices  are

free from defects in material and workmanship for the period specified below:

• CF, SD, MMC Flash Cards: Lifetime

• DataTraveler

®

USB Flash Drives and 15-in-1 Reader: 5 years

• TravelLite SD/MMC Reader: 1 year

For further details, see kingston.com/company/warranty.asp 

• Solid State: Flash storage devices, as semiconductor storage devices, have no

moving parts and thereby are not subject to the mechanical failure issues of hard
drives. Their overall data reliability enabled them to dominate the convenience-
oriented portable memory products market, operating silently with a zero decibel
noise level.

• Small Physical Size (or Form Factor): Flash storage devices are designed to be easily

transported. Convenience is an important criterion, especially for consumer and
corporate applications.

Kingston’s CompactFlash

cards have a rated error

specification of less 

than one (1) bit in

1,000,000,000,000,000

bits read, or one (1) 

bit per 10

15

bits read.
