Yes, you're right, we can forget from time to time ... now, what were we arguing about?

I mentioned, "... Moving data into RAM is handy if you modify it several times before writing it back into FLASH. and you said, "I'll grant you that one, but that is rarely a time critical operation."

It's not time-critical, but it surely relies on swapping the RAM and FLASH content.

There's a whole family of ultra-fast MCU's that relies on shadowing their FLASH to SRAM. That's how I know that the technology to do that exists.
