AMD offers a comprehensive set of physical layer memory interfaces and memory controllers for varied bandwidth, efficiency, and low latency requirements. Based on a rigorous characterization process to determine specifications, interface supports include DDR3 and DDR4 multi-rank DIMMs, including UDIMM, SODIMM, and RDIMM with DQS groups of x4 and x8. Refer to the following tools to plan your memory interface design and implementation:
AMD memory controllers are included in the Vivado™ IP Catalog at no extra charge.
Refer to the device data sheet for a full list of supported memory standards and maximum data rates.
AMD provides best-in-class tools to estimate memory performance, interface capacity, and power consumption to maximize performance-per-watt and accelerate design and implementation. Below are a variety of memory- and power-related tools to get started today.
