It is accessible via a dedicated serial interface optimized for fast and reliable data transmission. This interface allows several cards to be stacked by through connecting their peripheral contacts. These Hitachi MultiMediaCards are 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 pplications.MultiMediaCard allows the design of inexpensive 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 HB28H016MM2, HB28D032MM2, HB28B064MM2 and HB28B128MM2 MultiMediaCard will deliver enough capacity for all kinds of multimedia data: software/programs, text, music, speech, images, video etc.
