GUC Announces Progress in LPDDR4 IP and Reaffirms Commitment to DIMM Application of DDR3/4

Hsinchu, Taiwan - Global Unichip Corp (GUC), the Flexible ASIC LeaderTM and a leading mixed-signal IP provider, today announced two new additions to its 16nm process IP offerings: an LPDDR3/4 PHY/Controller combo in TSMC 16FF+ and 16FFC, respectively. In addition, the company reaffirmed its commitment to the growing DIMM market segment through a plan to tape out a DIMM-optimized DDR3/4 PHY/Controller IP set this year.

The new LPDDR4 IPs are capable of speed up to 3.2Gbps, as characterized in silicon interfacing SDRAMs in a memory system. The new IP in 16FF+ was silicon proven in July, 2015 and got first customer tape-out in 16FFC in Dec., 2015.

GUC's (LP)DDR3/4 PHY IP features auto training for higher speed and easy adoption, including PVT calibration, CA training, write leveling, gate training, read/write eye training, Vref training, per-bit deskew and clone path calibration. Various low power modes (Idle mode, IDDQ mode, deep sleep mode, frequency change mode) allow further power reduction.

"These faster, smaller and less power consuming new IPs demonstrated GUC's continued ability to innovate. They further solidified our place of leadership in offering complex IPs in the advanced TSMC processes to enable high-value SOC designs by our customers." said CJ Liang, SVP of R&D at GUC, in noting the significance of the new IPs.

As the world continues to see exponential growth in data, rendered by cloud based service and processed by data centers, the need for high density, high bandwidth and low latency memory solutions, such as DIMM based DDR systems, is increasing rapidly. Commenting on the company's plan to develop DIMM focused DDR3/4 interface IPs, Jim Lai, President of GUC said, "We have seen a surge in demand for DIMM based memory interface solutions. Customers are telling us that they need DDR4 PHY and Controller IPs with predictable performance in the face of the much more difficult signal integrity challenges that the DIMM environment poses, in order to build complete DIMM DDR systems. This plan to bring DIMM dedicated DDR4 IP set to market is our answer that the help is on the way."

GUC's in-house IP portfolio includes memory interface (DDR/ONFI), high-speed serial interface (SerDes), data converter, hardened ARM core, multimedia and fundamental IP (cell library, I/O, SRAM). GUC's IP eco-system provides the flexibility to work with IP from GUC, TSMC and other vendors, creating the widest range of design options.
