1. About Internal Memory Blocks This user guide describes the Altera megafunction IP cores that implement the following memory modes: ■ RAM:1-Port—Single-port RAM ■ RAM:2-Port—Dual-port RAM ■ ROM:1-Port—Single-port ROM ■ ROM:2-Port—Dual-port ROM Altera provides two IP cores to implement the memory modes—the ALTSYNCRAM and ALTDPRAM IP cores. The Quartus® II software automatically selects one of these IP cores to implement memory modes. The selection depends on the target device, memory modes, and features of the RAM and ROM. f For more information about IP cores, refer to the Introduction to Altera IP cores.
