Arria V devices support up to four hardened memory controllers for DDR3 and
DDR2 SDRAM. Each controller supports 8- to 32-bit components up to 4 gigabits (Gb)
in density with two-chip select and optional ECC. Arria V devices do not support
DDR3 SDRAM leveling.
Arria V devices also support soft memory controllers for DDR3, DDR2, LPDDR2, and
LPDDR SDRAM, RLDRAM II, QDR II, and QDR II+ SRAM for maximum flexibility.
Table 1–7 lists the external memory interface block performance.
