7. External Memory Interfaces in Arria V Devices

The Arria® V devices provide an efficient architecture that allows you to fit wide external memory interfaces to support a high level of system bandwidth within the small modular I/O bank structure. The I/Os are designed to provide high-performance support for existing and emerging external memory standards.
