The STM32H753 Reference Manual (RM0433) covers the integrated flash memory inside the microcontroller. It does not say why type of flash is integrated though (NOR or NAND). Is it possible to share what type of flash it is?

Hello @aaronlutzker and welcome to the community,

Is should be NOR Flash indeed. 

Nand Flash technology is used for data storage and not to execute code.

  • NOR Flash: Parallel architecture which makes random access faster and more efficient. Often used in applications that require faster read times, like firmware storage in microcontrollers.
  • NAND Flash: Serial architecture where multiple memory cells are connected in series to achieve higher density but slower random access. Commonly found in mass storage devices like USB drives and solid-state drives (SSDs).
