OPENEDGES and The Six Semi Announce Silicon Proven LPDDR5/4/4x PHY in Samsung Foundry 14LPP Technology Operating at 6400Mbps

 Oct 6, 2021 –-The Six Semiconductor Inc. (TSS) announces today that it has successfully brought up its Samsung Foundry 14LPP LPDDR5/4/4x PHY IP on its test chip, demonstrating performance of 6400Mbps in LPDDR5 mode. TSS is wholly owned by OPENEDGES Technology, Inc. (OPENEDGES) and teamed up with OPENEDGES to integrate their advanced PHY technology together with OPENEDGES memory subsystem IP.

Operating at 6400Mbps represents a 50% increase in memory bandwidth from LPPDR4’s top speed of 4266Mbps. Many smartphones today are already equipped with LPDDR5 DRAM, and the adoption of LPDDR5 in a wider range of applications such as edge devices, IoT, automotive, and AI inference are soon to follow. 

“The LPDDR5/4/4x PHY represents the second PHY architecture that we’ve developed, emphasizing on configurability, low power, and small PHY footprint. The team has done a great job from architecture to implementation, quickly developing a radically different PHY within a very short amount of time.”, said Ricky Lau, CTO of TSS.

“We are very excited to announce the successful bring up of our 14LPP LPDDR5/4/4x PHY, which only took less than two weeks from initial bring up to achieving 6400Mbps.”, said Alan Poon, VP Engineering of TSS.

The OPENEDGES and TSS team together develop network on a chip (NoC), memory controller, and DDR PHY, forming total memory subsystem solutions.
