Although Altera® FPGAs provide abundant on-chip internal SRAM memory resources, system bandwidth requirements often necessitate the use of large, fast off-chip memory devices. Altera memory controller intellectual property (IP) solutions are hardware-tested, drop-in design blocks that greatly simplify the local interface to complex memory devices such as double data rate (DDR) and single data rate (SDR) SDRAM, quad data rate (QDR) SRAM, zero-bus turnaround (ZBT) SRAM, and FCRAM. Altera solutions include both licensable IP functions and no-cost, open source design examples.
The Altera Stratix®, Stratix GX, and Cyclone® FPGA families include special I/O features designed specifically for interfacing with external memory devices. These features may include dedicated delay paths for data strobe signal alignment, multiple I/O registers to support DDR data transmission, and delay elements to reduce bus contention for ZBT protocols.
