DDR4 DRAM Memory Controller

Fully compliant to JEDEC standard JESD79-4A. It supports the popular industry standard AHB/AXI master, however, can be customized as per customer’s requirement.

DDR4 DRAM is no longer the memory only for Laptops and Servers, its ability to deliver increased performance and be highly reliable has led to its demand and adoption in multiple domains. At Arastu, we have developed a robust and flexible DDR4 DRAM Memory Controller IP and target to make the integration of DDR4 into your SoC a smooth one. The Design IP supports the popular industry standard AHB/AXI master, however, can be customized as per customer’s requirement. The controller is optimized for ASIC and FPGA designs.
