What does "Hard Memory Controller" number mean?

Question

Hi Intel support team,​I'd like to know how many DDR4 interfaces Arria 10 devices can support.​In table 5 &amp; 6 of the following website,https://www.intel.com/content/www/us/en/programmable/documentation/sam1403480274650.html#sam1403480019500,one resource is called "Hard Memory Controller" .​What's hard memory controller?For example, GX160 supports 6 hard memory controllers, could I say GX160 support up to 6 DDR4 memory interfaces (include controller and PHY)?​​Thanks.Chia-Ming Hung​​

Yes, you could potentially create up to 6 DDR4 memory interfaces though the interface widths would be limited by pin availability. Hard memory controllers are available in all the I/O banks of the device to provide flexibility for implementation. See this online training for an introduction to the memory interface architecture for these devices:
