Line 1: [[File:Flash-EEPROM.jpg\|thumb\|150px\|Flash-[[EEPROM]] in a Router - real MTD]] '''Memory technology devices''' (MTD) are a type of [[device file system#Devices\|device file]] in [[Linux]] for interacting with [[flash memory~~]], similar to [[Flash Translation Layer~~]]. 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. [[USB stick]]s, [[MultiMediaCard\|MMC]]s, [[Secure Digital\|SD]]s, [[CompactFlash]]es 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 [[Flash Translation Layer]].<ref>{{cite web \| url=http://www.linux-mtd.infradead.org/doc/general.html#L_overview \| title=Memory Technology Device Overview \| accessdate=1 September 2012}}</ref>
