Nor flash die erase
Web30 de set. de 2024 · The erase time of Nor Flash is studied by performing the erase operation under different conditions. The erase time at different ambient temperature, supply voltage and program/erase cycle are investigated. It is demonstrated that the obviously discrete is observed among different devices, and the significantly degradation is … 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).

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.

Once this number is reached, a row erase is mandatory. I've looked through a few other datasheets for other MCUs and some flash memory ICs, and so far the SAM D21 datasheet is the only place I've seen a limit like this specified.
