Writing same value or different values does not make it any easier for ram access. There are as many ports as vendors have decided.
I believe you better use register array indexed as ram

You are right if you consider the M9K, M144K to be RAMs. Somehow I thought these are generic memory blocks that can implement various types of memory: random access, FIFO, etc.

What is the most detailed information about the M9K (and the like) memory blocks available? I have the stratix iv hanbook (
http://www.altera.com/literature/hb/stratix-iv/stratix4_handbook.pdf) (chapter 3), but it still does not answer all my questions.
[QUESTION I STILL HAVE]
1. How do I write VHDL code to tell Quartus tools to put a certain memory into a M9K, or M144K, or other block?
