[[STM32]] [[MCU]]s all (?) use the following memory map to some degree.  There are minor differences so always check the relevant datasheet for the specific [[MCU]] being used.

The most interesting bit is the detail in the lower left corner specifying the two first blocks of memory.

Of these, the most interesting for a new developer are:

* Flash - 0x8000000

This is where you upload your application.

* RAM - 0x20000000 

This is where dynamic variables are allocated.

All internal peripherals are controlled through registers - each with a specific address.  But if using [[HAL]] it is not necessary to know these addresses.
