The Altera DDR and DDR2 SDRAM Controller Compiler comprises the DDR SDRAM
Controller MegaCore function and the DDR2 SDRAM Controller MegaCore function.
The MegaCore functions provide simplified interfaces to industry-standard DDR
SDRAM and DDR2 SDRAM devices.
The DDR and DDR2 SDRAM Controllers handle the complex aspects of using DDR or
DDR2 SDRAM—initializing the memory devices, managing SDRAM banks, and
keeping the devices refreshed at appropriate intervals. The DDR and DDR2 SDRAM
Controllers translate read and write requests from the local interface into all the
necessary SDRAM command signals.

Notes to
(1) For new Stratix II designs, use the DDR and DDR2 SDRAM High-Performance Controller.
(2) For more information on support for Stratix III devices with existing designs, contact Altera.
(3) For new Stratix III or Cyclone III designs, use the DDR and DDR2 SDRAM High-Performance Controller.
