SanDisk has wasted no time with the release of their 512MB microSD card that measures only 11mm x 15mm x 1mm. They had a slight advantage over everyone else since the TransFlash card design is what the microSD is based on. This means the official phasing out of the TransFlash memory card, but the 40+ handsets already using the technology will be compatible with the latest microSD. Future microSD devices will continue to operate with TransFlash cards, so no need to worry.

The SD Card Association (SDA) officially adopted the microSD today, this means the small sized memory card will be the driving force of expandable memory solutions in mobile phones.

The SD Memory Card, miniSD and now microSD are the dominating memory formats for wireless communication devices as of recent. Considering Motorola, Nokia, Samsung, Sharp, Panasonic, Toshiba, NEC and other leading marketers are members of the SDA, it’s pretty clear to see the path devices will be taking.
