Stricltly speaking it is not just a separate memory controller but on-chip RAM in a SoC which makes Rowhammer much harder.

Not really, the key distinction here is enforcing TZ using its own module, either via layout or separate controller..whether internal or not

OK, so only the controller as opposed to the delay in RAM access.

or the module, same controller but layout that enforces different modules should be fine as there's no chance for adjacent banks
