7.4 MULTIMEDIACARD (MMCmobile)

MultiMediaCards, like SD cards, are one of the smallest Flash cards available, about the size

as a postage stamp. They were introduced in 1997 and initially used in the mobile phone

and pager markets. Today, they are commonly used in digital cameras, MP3 players and

other digital devices. MMC cards are generally backward-compatible with SD cards (so they

can be plugged into SD slots) if the SD card’s copy protection management features are not

required by the host device. Kingston holds a position on the Board of Directors for the

MultiMediaCard Association, which sets the speci cations for MMC.

In addition, MMC cards come in smaller form factors, originally called RS-MMC (Reduced-

Size MMC) or RS-MMC DV (Reduced Size MMC — Dual Voltage). The original MMC speci-

 cation was updated from 3.x to 4.x. The new 4.x MMC cards are called MMCmobile

(replaces older RS-MMC DV).

The newer version of MMC cards launched in 2005 by the MultiMedia Card Association

supports revision 4.x of the speci cation and is backward-compatible with the older MMC

3.x and RS-MMC 3.x cards (now discontinued).

MMCmobile cards o er higher performance than older MMC cards, and MMCmobile cards

support lower voltage applications to reduce power consumption in portable devices. Kings-

ton has discontinued the older MMC, MMCplus and MMC-RS 3.x cards and only o ers the

newer, backward-compatible MMCmobile cards.

Kingston Flash Media Readers

Flash media readers allow Flash storage devices to be used as por table storage for computers

as well as for uploading or downloading of pictures, music, and other data without requiring

the original host device (such as a digital camera or MP3 player), and without any additional

drain on its batteries.

Flash media readers can enable the uploading and downloading of data at higher speeds

than a host device is capable of supporting; for example, a USB reader will be much

faster than a host device (such as a digital camera) using a serial interface. If a host device

does not support high-speed transfers, the faster reader will signi cantly reduce the data

transfer times.

Kingston o ers Flash media readers for the convenient attachment of Flash storage devices

to personal computers or notebooks.
