DDR5 Controller IP

Design IP

Overview

SmartDV’s DDR5 Controller IP is a high-performance solution designed to meet the demands of next-generation memory systems in computing, networking, and AI applications. Supporting data rates up to 6400 MT/s and compliant with the JEDEC DDR5 standard, the controller ensures efficient, low-latency, and high-bandwidth communication with DDR5 DRAM devices.

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. Advanced features such as multi-port access, command prioritization, low-power modes, and robust error handling make it ideal for high-performance and energy-efficient system designs.

Benefits

High-Speed Memory Access – Supports all DDR5 speed grades and device types (x4, x8, x16), with operational clock frequencies optimized for both ASIC and FPGA implementations. Delivers high throughput with programmable burst lengths (8, 16, 32) and low-latency read/write paths.
JEDEC-Compliant Command Scheduler – Fully compliant with DDR5 standards JESD79-5, JESD79-5A, and JESD79-5B v1.20. Supports all DDR5 command types, Sequential Burst, Auto Precharge, Precharge, ZQ Calibration, and Multipurpose Command (MPC) modes.
Flexible Configuration – Supports up to 64GB device densities and programmable page policies (Open/Closed). Integrates user-programmable timing features such as read/write latency, preamble/postamble/interamble, and DLL control.
Advanced Power Management – Includes support for self-refresh, power-down, Partial Array Self Refresh (PASR), Adaptive Refresh Management (ARFM), and temperature-compensated refresh. Enables maximum power saving mode and programmable clock frequency operation.
Robust ECC and RAS Features – Provides support for CRC on write/read operations, Post Package Repair (hPPR, sPPR, mPPR), MBIST PPR, and target row refresh for enhanced reliability, availability, and serviceability.
Seamless SoC Integration – Compliant with DFI 5.0 interface, supports up to 16 AXI ports with data widths up to 512 bits, and features multi-port arbitration, QoS-based in-port arbitration, and outstanding transaction control for optimized performance across interfaces.
