GDDR6 Controller

The Rambus GDDR6 controller core is designed for use in applications requiring high memory throughput including graphics, advanced driver assistance systems (ADAS), data center and artificial intelligence (AI).

How a 24G GDDR6 Memory Interface Subsystem works

Originally designed for graphics applications, GDDR6 is a high-performance memory solution that can be used in a variety of compute-intensive applications.

The GDDR6 controller fully supports the bandwidth and dual channel capabilities of the GDDR6 PHY. It maximizes memory bandwidth and minimizes latency via Look-Ahead command processing. The core is DFI compatible (with extensions for GDDR6) and supports AXI or native interface to user logic. The controller can be paired with 3rd-party or customer PHY solutions.
