The DDR4 Controller IP is a silicon-proven, JEDEC-compliant SDRAM controller supporting the full DDR4 speed family from DDR4-1600 to DDR4-3200. Its high-efficiency command scheduler maximises DRAM utilisation through bank-aware scheduling, adaptive page policy, and out-of-order execution while guaranteeing QoS for time-critical traffic.

The controller supports x8, x16, and x32 DRAM device widths, UDIMM/RDIMM/LRDIMM module types, and up to four independent channels for massive aggregate bandwidth. Integrated SEC/DED ECC with background scrubbing ensures data integrity for mission-critical server and networking deployments.

Features

Complete DDR4 Feature Set

High-Efficiency Scheduler

Out-of-order command scheduler with bank-group interleaving, adaptive open/closed page policy, and read/write turnaround optimisation for maximum DRAM efficiency.

Multi-Channel Architecture

Up to 4 independent DDR4 channels with optional channel interleaving for linear bandwidth scaling and redundancy in high-availability server designs.

SEC/DED ECC

Hardware Single-Error Correct / Double-Error Detect with background scrubbing, error injection for testing, and error logging via AXI4-Lite registers.

Adaptive Refresh

Temperature-aware adaptive refresh, post-package repair (PPR), and fine-granularity refresh for optimal power and reliability balance.

Power Management

Clock-stop, self-refresh, and power-down state management with automatic entry/exit for system-level power optimisation in always-on embedded designs.

RDIMM / LRDIMM Support

Registered and Load-Reduced DIMM support with RCD and DB for high-capacity 256 GB server memory configurations with full JEDEC compliance.

AXI4 Native Interface

Native AXI4 memory-mapped interface with 128/256/512-bit data bus width, transaction ID tracking, and 4-level QoS priority for SoC integration.

PHY Training

Automated read/write levelling, DQ/DQS training, VREF calibration, and ZQ calibration at power-up and periodic intervals for reliable high-speed operation.

Soft DDR4 PHY

Portable soft PHY for ASIC targets; FPGA variants use native hardened PHY primitives for verified silicon performance on all major FPGA families.
