Interfacing to single DDR4 SDRAM device

Hi, I am planning to design a board with Arria-10 GX FPGA and a single DDR4 SDRAM device, part no. MT40A1G8PM-083E. This doubt may appear silly, but I want to know whether I can have a functioni...

Hi Galfonz,

I am eager to know what makes you think that the performance will be terrible. If the interface is 1066, it means that I will have 2,133 Mbytes/sec (for x-16 chip). Considering highly pessimistic overheads of even up to 75%, I will still have more than 500 MBytes/sec. Don't you think this is huge enough. In my application the data rate coming into the board is only 50 Mbytes/sec. I need to do some processing, and some intermediate storage. Don't you think a single device will be good enough.
