The SD Card Association today presented the microSD memory card. They claim microSD is world's smallest removable storage card and as it's fully compatible with SanDisk's TransFlash cards it is supported by more than 40 cell phones from Motorola, Samsung, LC, Kyocera, Sagem and others.
In the mobile phone market, a small sized memory card is needed by handset vendors to provide memory expansion with the least impact on overall size. The addition of digital audio and cameras is driving this need for more memory in mobile phones. Conventional memory cards are, however, too big in dimensions for small mobile phone application. Hence, the SDA, with increasing focus on the mobile phone market has developed a new small sized SD card.
The SD Memory Card, along with the miniSD and now microSD cards, is the dominant memory format of choice for the wireless communications industry. The format is supported by SDA members Motorola, Nokia, Samsung, Sharp, Panasonic, Toshiba, NEC and other leading marketers of SD and miniSD(TM)-enabled mobile phones around the world.
The full interoperability of the microSD with TransFlash means that the microSD card can be used immediately in the millions of handsets that currently use TransFlash cards. Existing supporters of TransFlash will migrate their products to microSD. In the meantime, TransFlash cards will operate in new microSD hosts, and microSD cards will work in existing TransFlash hosts.
