According to OPENEDGES, its OPHY is the only 7nm LPDDR5X PHY IP currently available on the market.
OPENEDGES has a growing legacy of first-silicon success with its OPHY product line, following the successful bring-up of its GDDR6 PHY at 12nm in 2020, as well its LPDDR5/4 PHY at 14nm and 12nm in 2021 and 2022 respectively.
The company’s latest test chip is its third LPDDR OPHY iteration, fabricated using 7nm advanced process technology. It introduces support for LPDDR5X speed bins and beyond, on top of the previously supported LPDDR5, 4X, and 4 operating modes and speed bins.
As with its predecessors, the 7nm LPDDR5X/5/4X/4 OPHY test chip was brought up quickly in the lab, and has achieved 8533 Mbps operation, the current maximum data rate for LPDDR5X, with dual-rank DRAM. The LPDDR5X OPHY will demonstrate quad-rank support in the near future.
“With our latest 7nm LPDDR5X/5/4X/4 OPHY our IP Validation team has been able to build upon the success of our first-generation test chips,” said Jason Mangattur, Vice President of Silicon Operations at The Six Semiconductor of OPENEDGES. “We’ve expanded our lab capacity both in terms of equipment and engineering staff in order to meet the challenges of validating our highly sophisticated PHY that supports multiple LPDDR standards and data rates, multiple ranks, FSP configurations, and numerous DRAM vendors.”
OPENEDGES' latest LPDDR5X/5/4X/4 OPHY integrates key enhancements to its unique architecture, designed to enable maximum performance and flexibility while maintaining a competitive footprint compared to alternative LPDDR PHY solutions.
In addition to the introduction of LPDDR5X support up to 8533 Mbps, the available configuration has been expanded to both 1x16 and 1x32, verified and ready for customer integration.
“As the only 7nm LPDDR5X PHY available for immediate integration in the market, we have been gaining great customer traction throughout this year. I’m glad that our OPHY and technology node alignment is meeting the needs of our customers, creating value, and providing differentiation. Due to high customer demand, we are in the process of porting our OPHY to 6nm technology, another first for the market,” said Richard Fung, CEO of The Six Semiconductor of OPENEDGES.
