In the case that a "normal" filesystem is used, such as FAT, it isn't written out to the chips. NAND flash has special requirements about how it is written that prevent a normal FS from being used on it. There is a software layer between the filesystem the operating system sees and the flash chips. The operating system does not directly write to the flash chips unless it is using a flash filesystem. FAT32, ext2, and other non-embedded filesystems are not written directly to the flash.

Here is a company that sells flash chips that can be used with normal filesystems:

On that diagram the DiskOnChip is the physical device. You can see that there is quite a bit going on between what the operating system "sees" and what actually gets written to the chips.

If mathematically you end up with the wrong answer, try multiplying by the page number.
