Can a MCU run code directly from flash?

Question

I am using the STM32F4Discovery board and I nedd to run my code with a library which takes about 500KB when is compiled. I am skeptical if this system can support the memory requirements of the library. This MCU have 192KB of RAM and 1MB of flash. Can this mcu run code directly from flash?

If this microcontroller can´t support this requirements, there is a commercial available way to expand the RAM on this system? What technology should I use?

Answer 1

The whole point of MCU flash is to hold code. So, yes, it can execute code from there or the flash would be completely worthless.
