Designed for performance and power efficiency, the GDDR6 PHY enables applications requiring high memory throughput including graphics, advanced driver assistance systems (ADAS), data center and artificial intelligence (AI). With the Northwest Logic GDDR6 Controller it comprises a complete GDDR6 memory interface subsystem.
Originally designed for graphics applications, GDDR6 is a high-performance memory solution that can be used in a variety of compute-intensive applications.
The Rambus GDDR6 PHY is fully compliant to the JEDEC GDDR6 (JESD250) standard, supporting up to 18 Gbps per pin. The GDDR6 interface supports 2 channels, each with 16 bits for a total data width of 32 bits. At 18 Gbps per pin, the Rambus GDDR6 PHY offers a bandwidth of 72 GB/s. The PHY is available in advanced FinFET nodes for leading-edge SoC integration. Rambus works directly with customers to provide full-system signal and power integrity analysis, creating an optimized chip layout. Customers receive a hard macro solution with a full suite of test software for quick turn-on, characterization and debug.
The Northwest Logic GDDR6 controller fully supports the bandwidth and dual channel capabilities of the Rambus 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, OCP or native interface to user logic.
The Rambus GDDR6 PHY and Northwest Logic GDDR6 controller used together comprise a complete GDDR6 memory interface subsystem. Alternatively, these cores can be licensed separately to be paired with 3rd-party GDDR6 controller or PHY solutions.
