Web\$\begingroup\$ @JoelFernandes Although you technically could design a NOR flash to be capable of individual cell erasure, that's not done in practice. Because it requires a high negative voltage, not a 0 or a 1, to erase a cell, they link many cells up into blocks to perform this erase operation. Web19 de nov. de 2024 · Note that on this flash technology, a max number of 8 consecutive write is allowed per row. 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.
