Question about NOR flash erasing : r/embedded

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). Web4 de out. de 2024 · Finally, erase is done on per block-basis, but the smart algorithm ensures that all the cells have all the same "1" value. This is not trivial, as over-erase in NOR flash is deleterious: if the threshold voltage of one cell gets too low, you get with a stuck at 1 bitline.
