256Mbit (32Mx8bit / 16Mx16bit) NAND Flash Memory

Decoding the part number suggests that the device is SLC, single die, 3.3V supply, 32Mx8.

Datasheet first rev is 2003 so die design is probably about this age too. 90 nm ish? No deprocessing performed so not sure of exact node. Date code on the package is 2005 week 7.
