The INNOSILICON GDDR6 PHY is the world’s first silicon proven commercial GDDR6 IP, which is fully compliant with the JEDEC GDDR6 (JESD250) standard, supporting up to 16Gbps per pin. The GDDR6 interface supports 2 channels, each with 16bits for a total data width of 32bits. With speed up to 16Gbps per pin, the INNOSILICON GDDR6 PHY offers a maximum bandwidth of up to 64GB/s. And, the INNOSILICON GDDR6X PHY uses four-level pulse amplitude modulation (PAM4) signaling to extract more efficiency and higher data rates, which will be available in advanced FinFET nodes for leading-edge customer integration.
Graphics Double Data Rate (GDDR) is a modern type of Synchronous Graphics Random-Access Memory (SGRAM) with a high bandwidth DDR interface designed for use in graphics cards, game consoles, and high-performance computing. GDDR6/6X are currently the highest-bandwidth GDDR memory solutions, capable of supporting increased per-pin bandwidth (up to 21Gbps for GDDR6X, 16Gbps for GDDR6), lower operating voltages (1.35V), higher performance and lower power consumption compared to GDDR5/GDDR5X.
