GDDR7 Controller

The Rambus GDDR7 controller IP core is designed for use in applications requiring high memory throughput including artificial intelligence/machine learning (AI/ML), graphics, high-performance computing (HPC).

It supports 160 Gigabytes per second (GB/s) throughput for a GDDR7 memory device enabling next-level performance for AI accelerators and GPUs using GDDR7 memory.

How a GDDR7 Memory Controller Implementation in a Subsystem works

The GDDR7 controller supports all GDDR7 link features including PAM3 and NRZ signaling. Optimized for high efficiency and low latency across a wide variety of traffic scenarios, it offers low-power support (self-refresh, hibernate self-refresh, dynamic frequency scaling, etc.) and Reliability, Availability and Serviceability (RAS) features such as end-to-end data path parity, parity protection for stored registers, etc. Comprehensive memory test support and integration support for third-party PHYs are available.
