Figure 7–1. External Memory Interface Data Path Overview
Notes to
(1) You can bypass each register block.
(2) The blocks used for each memory interface may differ slightly. The shaded blocks are part of the Stratix IV IOE.
(3) These signals may be bidirectional or unidirectional, depending on the memory standard. When bidirectional, the signal is active during both read

Stratix IV I/O element (IOE) features.
Memory interfaces use Stratix IV device features such as delay-locked loops (DLLs),
dynamic OCT control, read- and write-leveling circuitry, and I/O features such as
OCT, programmable input delay chains, programmable output delay, slew rate
adjustment, and programmable drive strength.
For more information about I/O features, refer to the
chapter.
The ALTMEMPHY megafunction instantiates a phase-locked loop (PLL) and PLL
reconfiguration logic to adjust the phase shift based on VT variation.
