MMC Memory Card
A flash memory card that provides storage for cellphones, PDAs and other handheld devices. Introduced in 1997 with a 4MB capacity, the 32x24x1.4mm card weighs less than two grams. By 2005, storage increased to 2GB. The card uses flash memory for read/write applications or ROM chips (ROM-MMC) for static information, the latter widely used for adding applications to a Palm PDA.
One-time programmable (OTP) versions of the card are also available. MultiMediaCards (MMCs) are noted for their high transfer rates, up to 52 MB/sec. For more information, visit the MultiMediaCard Association at www.mmca.org.
