ABSTRACT
This article focuses on the version 4.0 of the MultiMediaCard (MMC) specification by the MultiMediaCard Association, which is a major expansion of the standard that opens innovative levels of sophistication and marketing opportunities to the digital imaging and mobile phone industries. To ensure smooth transition from previous versions of the MMC standards, the new specification defines backward compatibility paths for both legacy cards and host devices that accept MMCs. The multiple bus-width feature allows for host design flexibility and higher data transfer bandwidth. The extension of the maximum clock frequencies allows a higher data transfer rate and better compatibility to mobile phone architectural requirements.
