The microSD card is based on TransFlash, which was developed by SanDisk in cooperation with Motorola and is the world's smallest flash memory card form factor. SanDisk's TransFlash cards were recently adopted by the SD Card Association (SDA) and renamed "microSD."
The new microSD card is fully compatible with TransFlash card slots and is designed as a small, flash memory storage card for mobile phones and devices. The company will continue to support existing TransFlash product lines and will transition its handset customers and the retail channel to the renamed microSD card over the next several months.
Currently, the 512MB SanDisk microSD card is the largest capacity available in this form factor. The company expects to have 1GB microSD cards in limited quantities by late Q4 2005 and 2GB cards in 2006.
The SanDisk microSD card sold in retail channels includes an adapter that allows the card to be used in any device with a full size SD card slot. The SanDisk microSD card is being distributed through many of the 31,000 phone store outlets worldwide that offer SanDisk products.
