External memory interfaces including DDR, DDR2, DDR3, QDRII/+, and RLDRAM II provide caching or data storage space in the majority of end systems featuring FPGAs. Altera offers hardened physical interface (PHY) and soft controller external memory IP to maximize performance while still allowing for flexibility to accommodate various end systems. The External Memory Interface Handbook centralizes all the information you need to create a memory interface with the latest Altera FPGA families.
