true dual port == 2 x M20Ks

Seems like invoking true dual port (2 R/W ports) doubles the M20K resources - is this correct and if so where is it documented? I don't see it mentioned in https://www.altera.com/en_us/pdfs/lit...

How did you infer the memory block? If you inferred it from HDL, it's possible that you did it in a way that couldn't be synthesized with a single block. Did you have a look at the recommended hdl coding styles (https://www.altera.com/en_us/pdfs/literature/hb/qts/qts_qii51007.pdf) document? They show you how to write your HDL to be sure the synthesizer will pick it up as a single block with dual port.
