This chapter describes external memory interfaces available with the Stratix
device family and that family’s silicon capability to support external memory
interfaces. To support the level of system bandwidth achievable with Altera
Stratix IV FPGAs, the devices provide an efficient architecture to quickly and easily fit
wide external memory interfaces within their small modular I/O bank structure. The
I/Os are designed to provide high-performance support for existing and emerging
external double data rate (DDR) memory standards, such as DDR3, DDR2, DDR
SDRAM, QDR II+, QDR II SRAM, and RLDRAM II.
Stratix IV I/O elements provide easy-to-use built-in functionality required for a rapid
and robust implementation with features such as dynamic calibrated on-chip
termination (OCT), trace mismatch compensation, read- and write-leveling circuit for
DDR3 SDRAM interfaces, half data rate (HDR) blocks, and 4- to 36-bit programmable
DQ group widths.
The high-performance memory interface solution is backed-up by a self-calibrating
megafunction (ALTMEMPHY), optimized to take advantage of the Stratix IV I/O
structure and the TimeQuest Timing Analyzer, which completes the picture by
providing the total solution for the highest reliable frequency of operation across
process, voltage, and temperature (PVT) variations.
