Bonding Hard Memory Controller with Multi-Port Front End

Hi,

I want to bond two 16 Bit Hard Memory Controller (Arria V A1-Type) to get one 32 Bit Memory. Local I want to have a Multi-Port Front End (One 128 Bit Write, two 128 Bit Read). Is this possible?

in ArriaV handbook is written "You can bond one port of any data width (64, 128, or 256 bits) from two hard memory controllers to support wider data widths". This sounds as it is not possible to get a bonded Multi-Port DRAM.
