Definition of MTD(Memory Technology Device)
A 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.
Differences
Linux traditionally only knew block devices and character devices. Character devices were things like keyboards or mice, that you could read current data from, but couldn’t be seek-ed and didn’t have a size. Block devices had a fixed size and could be seek-ed. They also happened to be organized in blocks of multiple bytes, usually 512.
USB sticks, MMCs, SDs, CompactFlashes and other popular removable devices should not be confused with MTDs. Although they contain flash memory, this is hidden behind a block device interface using a FTL(Flash Translation Layer).
