6.5. Hard Memory Controller

The Cyclone® V devices feature dedicated hard memory controllers. You can use the hard memory controllers for LPDDR2, DDR2, and DDR3 SDRAM interfaces. Compared to the memory controllers implemented using core logic, the hard memory controllers allow support for higher memory interface frequencies with shorter latency cycles.

The hard memory controllers use dedicated I/O pins as data, address, command, control, clock, and ground pins for the SDRAM interface. If you do not use the hard memory controllers, you can use these dedicated pins as regular I/O pins.
