WebIn my experience, all of the older flash chips allow you to change any 1 bit to a 0 bit without an erase cycle, even if that bit is in a page or even a byte that has already had other bits programmed to zero -- a page of flash can be programmed multiple times between erases. (This is called "multiple-write" in the YAFFS article). WebSectors are the smallest logical unit a hard drive cares about, it used to 512b, but most modern drives use 4096b.
