• 7.4 MULTIMEDIACARD (MMC,MMCplus,MMCmobile)
  MultiMediaCards, like SD cards, are one of the smallest Flash cards available, about
  the size of 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,
  mobile phones, and MP3 players. 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. The MultiMediaCard
  Association, on which Kingston holds a position on the Board of Directors, sets the
  specifications 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
  Kingston’s MMCplus
  is based on the latest
  MultiMediaCard System
  Specification Version 4.0,
  a five-fold improvement
  in performance over
  previous MMC standards.
  
  original MMC specification was recently updated from 3.x to 4.x. The new 4.x MMC
  cards are called MMCplus (replaces older MMC) and MMCmobile (replaces older RSMMC
  DV).
  The newer version of MMC cards launched in 2005 by the MultiMedia Card
  Association supports revision 4.x of the specification and is backward-compatible with
  the older MMC 3.x and RS-MMC 3.x cards (now discontinued).
  MMCplus and MMCmobile cards offer higher performance than older MMC cards, and
  MMCmobile cards support lower voltage applications to reduce power consumption
  in cell phones. Kingston has discontinued the older MMC and MMC-RS 3.x cards and
  only offers the newer, backward-compatible MMCplus and MMCmobile cards. A new,
  thumbnail-sized MMC card, called MMCmicro, is expected in early 2006.
  MMC cards are designed for use in many popular portable devices. MMCmobile cards
  are the mobile platform form factors designed for use in cell phones and other portable
  devices. They are a fraction of the size of a standard MMCplus card and, when using
  the supplied Kingston adapter, can be used in standard MMCplus device slots (e.g., in
  Flash media readers).
