What is MTD devices?

I'm configurating a new kernel but I'm not sure what MTD devices is. Will I need it? Who needs it, and why?

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).

(I realize this is an old post but it is exactly the question I had...)

So thanks for that technical explanation of what MTD devices are, but that doesn't really help me. I have a typical desktop PC. Maybe it would help if someone could give some examples of MTD devices?

I guess to be more specific: do I need MTD support enabled to use USB sticks for example? Are there other commonly used devices that would need MTD support enabled in order to work?

Thanks for any help!

You dont really need MTD drivers unless until you use DISKONCHIP and other on board flash chips.

For USB sticks it is not needed.

If u r building new kernel with latest versions 2.6.x or higher u will find USB as subtitle under DRIVERS title.
