Please note: Some of the listed capacity is used for formatting and other

functions and thus is not available for data storage. Please see Section 2 for details.

• High-Performance: Kingston’s Elite Pro/Ultimate Flash cards and Hi-Speed DataTraveler

USB Flash drives are faster than many standard Flash products and many competitive

products. Kingston’s engineers test and select high-performance controllers to ensure that

Kingston’s Flash cards are among the performance leaders. Please see the Appendix for

information about USB and Hi-Speed USB performance. Kingston standard Flash products

o er moderate performance levels for general purpose applications.

• Low Power Consumption: Unlike standard DRAM memory that needs to be constantly

powered on to maintain its data, Flash memory is non-volatile and does not require

power to maintain its data. Flash memory’s low power consumption results in longer

battery life for the host device.

• Plug-and-Play Support: Kingston’s Flash memory line supports plug and play. With

plug-and-play technology and compatible computer operating systems, a Flash storage

device can be inserted into a computer or a Flash media reader and be quickly recognized

and accessed by the computer.

• Hot-Swapping Support: Hot-swapping allows for plugging or unplugging Flash storage

devices into a compatible computer or reader without needing to power o and restart the

computer. This feature enhances the portability and convenience of Flash storage devices

for transferring data, pictures or music between two computers or devices.

Non-Volatile NOR and NAND Flash Technologies

Unlike Dynamic Random Access Memory (DRAM), Flash memory is non-volatile. Non-

volatile memory retains data even without being powered-on. For example, when a computer

is turned o , all data that was in the computer’s DRAM memory is lost; however, when a

Flash storage device is removed from a digital camera, all data (and pictures) remains saved

on the Flash storage device. The ability to retain data is key for Flash memory applications

such as digital  lm for digital cameras, cell phones, PDAs and other transportable devices.

There are two major technologies of Flash memory: NOR and NAND. Each technology

has strengths that make it ideal for di erent kinds of applications, as summarized in the

table below:
