It depends on the mix of circuits. Memory don't follow same design rules as logic so can scale quite well. Logic density may well be limited more by power dissipation than by design rules. In other words you can pack some circuits a lot denser than others. I do agree that it is frustrating for someone from the outside to understand exactly what kind of scaling one can expect.
