It's called Journalling Flash File System (JFFS2) in its current incarnation.

David Woodhouse spoke about it at LCA 2002. I can't find a copy of his paper 
from LCA, but the OLS version is linked off:
http://sources.redhat.com/jffs2/

Its an interesting idea, but note that not all devices actually require 
wear-leveling to be implemented in the filesystem. I'm not really across 
which technologies implement wear leveling themselves, and which need 
something like JFFS2. Perhaps someone else can clarify this bit.
