Daxiwen mentioned the byte enable example in the "Recommended HDL Style" document. You say, that the recommended HDL style does not use more RAM than required. So what's the problem?
Did you try the method suggested in the document?

Yes, the "ram1" module in the code in my original post is the method suggested in the document. The problem is that the "data_width" parameter doesn't work.

What do you mean with module body? The memory module or calling function? Accessing the RAM in bytes as required by the recommended coding style involves a change in the memory module. But it can be completely hidden inside the module.

I mean the memory module, and yes, it can be hidden inside the module with a set of hard coded memories selected by generate blocks. That seems to be what i need to do. I usually try to avoid that approach if possible because it does not scale well if more than one parameter needs to be handled this way, but in this case it seems to be necessary.
