Debian Memory Requirements

Each Debian release and architecture has it's own (minimum) RAM requirements, which mainly depends of the type of installation (Graphical Desktop...).

This requirement is given in the "Debian Installation guides" [http://www.debian.org/releases/] ([http://www.debian.org/releases/stable/i386/ch02s05.html Stable/i386])

Available Memory

Gnome user can use Hardinfo (in Menu Applications/System Tools) to know the installed/available RAM.

free is the unix standard command to display amount of free and used memory in the system. For example :

$free
             total       used       free     shared    buffers     cached
Mem:       2067696     679244    1388452          0     111500     123236
-/+ buffers/cache:     444508    1623188
Swap:       998572     368976     629596

MTD (Memory Technology Device)

Memory Technology Device (MTD) Subsystem for Linux Design is a generic Linux subsystem for memory devices, especially Flash devices.

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, ["FFS2"], etc., but will only need to provide simple routines for read, write and erase. Presentation of the device's contents to the user in an appropriate form will be handled by the upper layers of the system.
