NAME
mem, kmem - core memory
DESCRIPTION
mem is a special file that is an image of the core memory of
the computer. It may be used, for example, to examine, and
even to patch the system.
Byte addresses in mem are interpreted as memory addresses.
References to non-existent locations cause errors to be
returned.
Examining and patching device registers is likely to lead to
unexpected results when read-only or write-only bits are
present.
The file kmem is the same as mem except that kernel virtual
memory rather than physical memory is accessed.
FILES
/dev/mem, /dev/kmem
