The good thing about microcontrollers ..

.. is that RAM is pristine.  Apart from having to deal with hardware
interfaces, there are very little limitations about how to use memory.

( Forget for a moment the possibility to reserve _part_ of the RAM and
Flash for code with standard calling conventions and non-moving flat
memory layout. )

The point is that building a more useful graph memory on top of
RAM/Flash combo is doable when you can design the whole system.
