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 an MTD but a block device

USB sticks, MMCs, SDs, CompactFlashes and other popular removable devices should not be confused with MTDs. Although they are also called "flash", they are not Memory Technology Devices.[1]
