Stratix® II和Stratix II GX器件对DDR存储器(如DDR2/DDR SDRAM、QDRII+/QDRII SRAM和RLDRAM II接口)提供支持，而Arria GX器件支持DDR2和DDR SDRAM接口。
Stratix® II and Stratix II GX devices offer support for double data rate
(DDR) memories, such as DDR2/DDR SDRAM, QDRII+/QDRII SRAM,
and RLDRAM II interfaces, while Arria® GX devices support DDR2 and
DDR SDRAM interfaces. Applications with these memory interfaces
include PCs, embedded processing, image processing, storage,
communications, and networking.
