Removable storage maker Sandisk's TransFlash specification was adopted by the SD Card Association as an industry standard on Wednesday, and will be sold under the microSD brand.
TransFlash/MicroSD cards are the smallest flash memory cards commercially available, measuring 11mm × 15mm × 1mm. TransFlash has already proved popular with mobile phone makers — including Motorola and Samsung — who are keen to boost the memory capability of their devices without making them too large.
Currently, the most capacious TransFlash cards on the market have a 256MB capacity, but SanDisk said on Wednesday that it plans to launch a 1GB microSD card by the end of 2005 and a 2GB card in 2006.
Because TransFlash has primarily been used by mobile phone makers, few other electronic devices directly support it. SanDisk has addressed this by offering an adaptor that converts a TransFlash card into a standard SD card.
