GPU GDDR6 PHY and controllers

GDDR6, an abbreviation for graphics double data rate type six synchronous dynamic random-access memory, is a modern type of synchronous graphics random-access memory (SGRAM) with a high bandwidth ("double data rate") interface designed for use in graphics cards, game consoles, and high-performance computation. The finalised specification was published by JEDEC in July 2017. GDDR6 offers increased per-pin bandwidth (up to 16 Gbps) and lower operating voltages (1.35 V), increasing performance and decreasing power consumption relative to GDDR5/GDDR5X.

The Innosilicon GDDR6 PHY is the world’s first silicon proven commercial GDDR6 IP, it is fully compliant to the JEDEC GDDR6 (JESD250) standard, supporting up to 16 Gbps per pin. 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 Innosilicon 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 Innosilicon system-aware design methodology used for IP Cores delivers a customer focused experience with improved time-to-market and first-time-right quality. Innosilicon 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.
