What’s a Memory Technology Device? According to the MTD project homepage . . . The Memory Technology Device (MTD) subsystem for Linux provides generic support Linux for various types of memory devices, especially Flash devices such as the M-Systems DiskOnChip. The aim of the system is to make it simple to provide a driver for new hardware, by providing a generic interface between the hardware drivers and the upper layers of the system. Hardware drivers need to know nothing about the storage formats used, such as FTL (Flash Translation Layer), FFS2, etc., but will only need to provide simple routines for read, write, erase, and query. Presentation of the device’s contents to the user in an appropriate form is handled by the upper layers of the system. In particular, an open source driver was developed based on specifications and sample hardware provided to the MTD project by M-Systems. At this point, the MTD subsystem is part of the standard Linux kernel (2.4.0 and later).
