General Description
The SIEMENS MultiMediaCard R0002 is a highly integrated read only memory (ROM) with serial
and random access capability using an innovative ultra high density cell design in the memory
array. It is accessible via a dedicated serial interface optimized for fast and reliable data transmis-
sion. This interface allows several cards to be stacked by through connecting their peripheral con-
tacts. The R0002 is fully compatible to a new consumer standard, called the MultiMediaCard system
standard defined in the MultiMediaCard system specification [1].
The MultiMediaCard system is a new mass-storage system based on innovations in semiconductor
technology. It has been developed to provide an inexpensive, mechanically robust storage medium
in card form for multimedia consumer applications. MultiMediaCard allows the design of inexpen-
sive players and drives without moving parts. A low power consumption and a wide supply voltage
range favors mobile, battery-powered applications such as audio players, organizers, palmtops,
electronic books, encyclopedia and dictionaries. Using very effective data compression schemes
such as MPEG, the MultiMediaCard will deliver enough capacity for all kinds of multimedia data:
software/programs, text, music, speech, images, video etc.
