The MultiMediaCard Association (MMCA) is the open standard memory card organization, promoting worldwide adoption of storage media and peripheral I/O devices designed especially for mobile phones and digital imaging devices. It enables a myriad of applications to come together and share digital media contents.

The MMCA oversees standardization activities for removable storage media, including MMCplus™, MMCmobile™ and MMCmicro™ Cards; SecureMMC; ATA on MMC; Multiple Interface Cards; and MMC I/O.

MMCplus™, MMCmobile™ and MMCmicro™ Cards, built to the latest MMC standards v4.2, offer wider bandwidths and the highest data transfer rates among memory cards available in the market today.

Founded in 1998, the MMCA provides a global forum for memory card and semiconductor component suppliers, software vendors and manufacturers of mobile electronic devices who jointly endorse and promote the worldwide adoption of MultiMediaCards and the MMC standards.

MMCA Principles:

• The organization is dedicated to open industry standards
• These standards are established consensually, with the equal participation of MMCA members
• Product interoperability and compliance are integral to the specifications and standards.
