Yaffs is designed around how NAND flash works and does not erase and write at 
the same time.

NOR flash allows you to do an erase suspend because erases are so slow. That 
allows you to suspend an erase, do some writes or reads then reenable the 
erase.

NAND erases are a lot faster so this feature is not required,
