DRAM and SRAM with Cyclone III

If the DRAM is DDR or DDR2, use the altmemphy megafunction even if you choose not to use the DDR/DDR2 SDRAM High Performance Controller MegaCore for the controller logic. If you do use the MegaCore, it will set up altmemphy automatically.

Even if you create the datapath yourself instead of using altmemphy, you should use the recommended pins for DQ and DQS. But it is strongly recommended that you use the free altmemphy if you are using a memory type supported by that megafunction.

I don't know anything about the particular pins you mentioned (and I didn't try to look it up).
