This makes no sense. If the flash chip has 256 sectors (aka "erase
units"), you can always erase each individual sector without any
influence on the other 255 sectors.

Niklaus Wirth has lamented that, whereas Europeans pronounce his name
correctly (Ni-klows Virt), Americans invariably mangle it into (Nick-
les Worth). Which is to say that Europeans call him by name, but
Americans call him by value.
