microSD Will Replace SanDisk’s TransFlash

by Reads (9,555)

The SD Card Association (SDA) plans to finalize this Spring the specifications for microSD, a new, super-compact memory card format.

Some might question the need for yet another small memory card format, as quite a few new ones have been created in recent months. However, the microSD card will be completely compatible with SanDisk’s TransFlash format, and SanDisk plans to transition its TransFlash line to the microSD standard the third quarter of this year.

SanDisk TransFlash has been widely adopted by key handset manufacturers around the world. The microSD card is supported by the more than 800 members of the SD Association and can be used immediately in the millions of handsets that currently use TransFlash.

“History has proven that manufacturers and consumers alike prefer a single industry standard card format that is broadly supported and that unifies the removable Storage requirements both of mobile handsets and consumer electronics. We welcome the impending adoption of microSD as the new industry standard for mobile devices,” said Yoram Cedar, an SDA board member and senior vice president of engineering and emerging markets at SanDisk.

Adapters will be available so users can insert a microSD card into a standard SD card slot.

More About TransFlash

A TransFlash card is only 15 mm by 11 mm by 1 mm. It is intended primarily for smartphones, where the size constraints are even more stringent than they are in handhelds.

TransFlash Card Unlike other memory card formats, TransFlash has been designed to mostly stay in the device and act as its built-in memory. However, it can be removed to be plugged into another device to transfer files. It also allows the smartphone’s on-board memory to be easily upgraded.

The highest capacity TransFlash card currently available is 512 MB.
