My M9K blocks get always synthesized away!

Well, if Quartus detects that your memory is never written and holds a constant data pattern it can optimize it away and replace it with simple logic.

Quartus is pretty smart about optimizing away logic it detects as not being used (eg, generated logic that does not drive any other logic can be eliminated).
