What is MMC?
MultiMediaCards (MMCs) are small, removable memory cards used increasingly in mobile phones and digital cameras for storing digital music, games, address books and photos, as well as for enabling a myriad of applications to come together and share digital media including content protected by digital rights management (DRM) .
Memory card usage in mobile phones is increasing at a rapid pace. It is projected that by 2006, one third of all mobile phones will have a slot for removable memory cards. MMCs have already been adopted by four of the top five mobile phone manufacturers, and are expected to have the fastest growth among the various memory card formats in that market. One reason for MMCs? growing acceptance is that the MultiMediaCard technology is an open, royalty-free standard.
MMCplus? and MMCmobile? Cards, based on the latest MMC System Specification Version 4.0, are the most advanced memory cards available today, offering the highest transfer speeds (up to 52MB/sec, or 416 Mbits/sec) , and the greatest flexibility, including support for dual-voltage operation (1.8 and 3/3.3V) , and multiple bus widths (x1, x4 and x8 bit) . While the new cards have 13 pins to accommodate the additional features, they are backwards compatible with previous version MMCs (7-pins) , thus bridging the mobile storage applications of yesterday, today and tomorrow.
MMCs, including MMCplus and MMCmobile Cards, are available as rewritable data storage cards, typically based on flash memory technology, and read-only memory (ROM) cards. MMCs are energy-efficient and cost-effective for consumer electronic devices. With storage capacities up to 1 Gbyte (approximately 640,000 book pages) and higher, the cards are compatible with products from hundreds of the world?s leading consumer electronics firms, including Canon, Casio, Eastman Kodak, Hewlett Packard, Hitachi, JVC, Motorola, Nokia, Samsung, Sanyo, Siemens and many others.
In addition to being a data storage accessory in mobile devices, MMCs open new and sophisticated marketing opportunities for value-added applications and services on mobile devices for ODMs, OEMs, network operators and content providers. Consumers will soon see an explosion of multimedia content both on preloaded MMCs in stores, as well as on downloadable content from mobile phone networks to be stored on MMCs, enabling new services in attractive new devices for the growing mobile community.
Coming soon from the MultiMediaCard Association is a new standard for security on MMCs: Secure MultiMediaCard (SecureMMC) specification version 2.0 complying with OMA DRM 2.0 and mobile security requirements. It addresses the security requirements of future consumer, business and industrial applications, particularly in portable devices.
