Product Brief

How GDDR6 PHY works

The Rambus GDDR6 (Graphics Double Data Rate) Memory PHY enables the communication to and from high-speed, high-bandwidth GDDR6 SGRAM (Synchronous Graphics Random Access) memory. Originally designed for graphics applications, GDDR6 is a high-performance memory solution that can be used in a variety of high-performance applications that require large amounts of data computation like artificial intelligence (AI), crypto mining, deep learning, autonomous vehicles, and high-speed networking.

GDDR6 PHY Subsystem Example

The Rambus GDDR6 PHY will be fully compliant to the JEDEC GDDR6 (JESD250) standard, supporting up to 16 Gbps per pin, and is available on TSMC 7nm process. The GDDR6 interface supports 2 channels, each with 16 bits for a total data width of 32 bits. With Speeds up to 16 Gbps per pin the Rambus GDDR6 PHY will offer a maximum bandwidth of up to 64 GB/s. This PHY will be available in advanced FinFET nodes for leading-edge customer integration. The Rambus system-aware design methodology used for IP Cores delivers a customer focused experience with improved time-to-market and first-time-right quality. Rambus offers flexible delivery of IP cores and will work directly with the customer to provide a full system signal and power integrity analysis, creating an optimized chip layout. In the end, the customer receives a hard macro solution with a full suite of test software for quick turn-on, characterization and debug.
