The Stratix IOE operates in bidirectional DDR mode by combining the
DDR input and DDR output configurations. Stratix device I/O pins
transfer data on a DDR bidirectional bus to support DDR SDRAM. The
negative-edge-clocked OE register holds the OE signal inactive until the
falling edge of the clock. This is done to meet DDR SDRAM timing
requirements.
External RAM Interfacing
Stratix devices support DDR SDRAM at up to 200 MHz (400-Mbps data
rate) through dedicated phase-shift circuitry, QDR and QDRII SRAM
interfaces up to 167 MHz, and ZBT SRAM interfaces up to 200 MHz.
Stratix devices also provide preliminary support for reduced latency
DRAM II (RLDRAM II) at rates up to 200 MHz through the dedicated
phase-shift circuitry.

To find out more about the DDR SDRAM specification, see the JEDEC
web site (www.jedec.org). For information on memory controller
megafunctions for Stratix devices, see the Altera web site
(www.altera.com). See AN 342: Interfacing DDR SDRAM with Stratix &
Stratix GX Devices for more information on DDR SDRAM interface in
Stratix. Also see AN 349: QDR SRAM Controller Reference Design for
Stratix & Stratix GX Devices and AN 329: ZBT SRAM Controller Reference
Design for Stratix & Stratix GX Devices.
In addition to the required signals for external memory
interfacing, Stratix devices offer the optional clock enable signal.
By default the Quartus II software sets the clock enable signal
high, which tells the output register to update with new values.
The output registers hold their own values if the design sets the
clock enable signal low. See
