STM32F767 QSPI vs FMC

Hi Community!

For a new project I need both external RAM and external

FLASH memory (from which code should also be executed) on a

STM32F767BG.

Now I'm faced with the question of what makes more sense:

• SRAM on FMC and Flash on QPSI

• Or SRAM and Flash both on the same FMC

Can you say in general what is more efficient and performant with regard to

Waiting and access times? Can you also say in general whether NOR or NAND

Flash is preferable?

Cheers
