That is correct....
The MicroSD form factor is used as a removable module for phones. You can also buy a reader in the standard SD card form factor that the MicroSD plugs into, so that you can plug it into your desktop or laptop.
However, MicroSD/transflash is being offered by Sandisk as an embedded solution, making the claim to device developers, that it's a much simpler process because of its ability. Compared to a raw flash development cycle with associated hardware obstacles.
This offering started before the MicroSD name came along...it was offered starting with the name Transflash.
A whole new ball game is now starting with regard to SD form factors....HC...or high capacity.....up to 32GB.
The new offerings are starting with standard card format SDHC....SDminiHC.....MicroSDHC....
It basically means they are moving to a new method of addressing within the memory to allow the 32GB....starting 2007 into 2008 and beyond.
They're moving from FAT12 and 16 abilities into FAT32 capability.
The new offerings will not be backward compatible to older CE devices not have the HC designation. Your older version cards will be forward compatible to HC....subtly allowing you to move forward and throw your old CE devices to the back of the draw, and the beat goes on.
For HC...they're moving from the typical Cluster addressing to byte addressing to allow it to happen.
My concern is the manner they use to manage the FAT .....do they do it in the same manner e.Digital does. How do they manage the virtual tables? Within the flash, or , status quo through RAM processes?
I note that some vendor SD offerings, consider some form of power preservation within their specs. Saving power is managed according to RAM resource.....have these offering diminished the normally associated RAM resource?
Has Sandisk and the likes...done this with Transflash embedded offerings now MicroSD, now moving into microSDHC?
