DDR4 Controller IP

Design IP

Overview

SmartDV’s DDR4 Controller IP is a high-performance, feature-rich solution designed to manage seamless communication between processors and DDR4 memory devices in high-bandwidth applications. It supports JEDEC-standard DDR4 interfaces and ensures efficient, low-latency memory transactions across a range of embedded, networking, and data center systems.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Its robust architecture supports advanced features such as multi-port access, ECC support, and configurable burst lengths, making it an ideal choice for performance-critical memory subsystems.

Benefits

High-Speed Memory Access – Supports high clock speeds in both ASIC and FPGA, with low-latency read/write paths and programmable burst length (4/8) and burst types (sequential, interleave)
Flexible Configuration – Supports up to 16GB device density, DDR4 x4/x8/x16/x32 devices, and up to 16 AXI ports with data widths up to 512 bits
Robust Scheduling Logic – Includes in-port and multi-port arbitration, QoS-based scheduling, and configurable outstanding transactions for optimized throughput
Advanced Power Management – Supports power-down modes, clock stop, maximum power saving, gear-down, and fine granularity refresh modes
Reliable and Secure Data Handling – Supports ECC, CRC read/write, DBI (Data Bus Inversion), command/address parity, and post-package repair (PPR)
AXI-Compatible Interface – Provides seamless AMBA AXI integration with programmable write/read latency and reorder support for performance tuning
Built-In Initialization & Training – Automates JEDEC-compliant initialization, write leveling, ZQ calibration, read preamble training, and DQ Vref training
Programmable Operation Modes – Supports closed/open page policy, programmable burst order, latency, preamble, and clock frequency control
Comprehensive Debug & Test – Includes MBIST PPR, connectivity test mode, multipurpose registers, on-the-fly protocol/data checking, and CT/DLL diagnostics
