There's been a mistake when extracting the geometry of the W35N02 and W35N04 chips from the datasheet. There is a single plane, however there are respectively 2 and 4 LUNs. They are actually referred in the datasheet as dies (equivalent of target), but as there is no die select operation and the chips only feature a single configuration register for the entire chip (instead of one per die), we can reasonably assume we are talking about LUNs and not dies.
