Thank you very much for your correction.
I think, this should also be corrected :-
http://www.linux-mtd.infradead.org/tech/nand.html says
that :-
There are four layers of software
JFFS2: filesystem driver
MTD: Memory Technology Devices driver
NAND: generic NAND driver
Hardware specific driver
It should be :-
There are five layers of software
JFFS2: filesystem driver
Flash Translation Layer: FTL (for NOR) or NFTL (for
NAND)
MTD: Memory Technology Devices driver
NAND: generic NAND driver
Hardware specific driver
Am i again wrong ?
Thank you for your help.
