If used together with the REGION_ALIAS feature, this becomes more clear.
Often, the MEMORY commands and SECTIONS commands are kept in different linker scripts and the REGION_ALIAS feature is used to keep them independent.
This way, we can use the same linker script containing the SECTIONS commands and just switch the linker script containing the MEMORY commands for different targets.
Then, one target might map RAM2 to some flash region, while the other target simply maps to the same ram region.
