DDR-4 Controller

The DDR4 Controller IP Core is a high-speed, silicon-proven memory interface solution, fully compliant with JEDEC DDR4 SDRAM standards. Designed for seamless integration into FPGA, ASIC, and SoC platforms, the core supports data rates up to 3200 MT/s and advanced features such as multi-port arbitration, ECC, and low-power operation. With flexible APB and AXI host interfaces, the controller enables rapid, robust connectivity to high-density DDR4 memory devices for demanding embedded, consumer, and enterprise applications. Its architecture features multi-port arbitration, allowing simultaneous access from multiple system masters without bottlenecks, and built-in Error Correction Code (ECC) capabilities for enhanced data integrity and system reliability.This versatility makes it the ideal choice for designers seeking to maximize memory bandwidth, minimize latency, and ensure long-term reliability in mission-critical embedded, consumer, and enterprise platforms
