Memory technology devices (MTD) are a new type of device file in Linux for interacting with flash memory. The MTD subsystem was created to provide an abstraction layer between the hardware-specific device drivers and higher-level applications. Although character and block device files already existed, their semantics don't map well to the way that flash memory devices operate.

Not a MTD but a block device

Do not be confused by USB sticks, MMCs, SDs, CompactFlashes and other popular removable devices. Although they are also called "flash", they are not MTD devices.[1]
