World’s first DDR5 DRAM module has focus on power

Technology News |
By Nick Flaherty

The DDR5 memory module is supports transfer rate of 4.8 to 5.6Gbit/s, 1.8 times faster than the previous generation, at 1.1V rather than 1.2V. This reduces the power consumption by 20 percent, which is key for data centre applications, and integrates the power management IC (PMIC) into the module for the first time.

The company has supplied samples of the 16Gbit DDR5 memory to major partners including Intel, and has completed various tests and verification of its functions and compatibility. 3D sacking of die using through-silicon-via (TSV) interconnect enables a capacity of 256Gigabytes in a single package.

SK Hynix has also been working with System-on-Chip (SoC) manufacturers such as Renesas to verify the functions of DDR5, including the register clock driver (RCD) in the module that ensures signal quality between the transmitter and the receiver by amplifying commands and data signals applied to memory from memory controllers. It has also been testing the PMIC in the module.

The Error Correcting Code (ECC) inside the chip that can correct even 1-bit-level errors by itself. With the ECC, the reliability of applications will be increased by 20 times.

“Intel partnered closely with memory leaders including SK hynix on the DDR5 spec development starting with early architecture concepts through JEDEC standardization,” said Carolyn Duran, Vice President of Intel’s Data Platforms Group and GM of Memory and IO Technologies. “In addition, we worked collaboratively with SK hynix on silicon development by designing and testing prototypes to ensure DDR5 meets its performance goals and are fully ready for our mutual customers.” 

“As SK hynix has launched World’s First DDR5 DRAM, the Company could lead the future technology trend in global DRAM market,” said Jonghoon Oh, Executive Vice President and Chief Marketing Officer (CMO) at SK hynix. “SK hynix will focus on the fast-growing premium server market, solidifying its position as a leading company in server DRAM.”

The DDR5 standard was published by JEDEC (JEDEC Solid State Technology Association) in July, and market researchers Omdia predict DDR5 demand will begin to grow in 2021, and taking 10 percent of the total global DRAM market in 2022 and 43 percent by 2024.

Synopsys, Renesas, Montage Technology and Rambus have also stated their commitment to the continuing cooperation in creating the DDR5 ecosystem.

“Synopsys has collaborated with SK hynix to deliver highly reliable DDR5 solutions for advanced high-performance computing SoCs requiring ultra-fast and high-capacity memory subsystems,” said John Koeter, senior vice president of marketing and strategy for IP at Synopsys. “Our silicon-proven DesignWare DDR5/4 IP has been validated using numerous SK hynix DDR5 RDIMMs at up to 6400 Mbps, helping designers minimize risk and meet their high-performance requirements of data-intensive SoCs.”

“As the leading supplier of memory interface products for every generation of memory over the last twenty years, we pride ourselves on strong engagements with our key partners and customers. Renesas has worked closely with SK hynix to qualify a complete portfolio of DDR5 products for server, client and embedded markets,” said Rami Sethi, Vice President and General Manager of Renesas’ Data Centre Business Division.

“Montage Technology is thrilled to partner with SK hynix on enabling the DDR5 memory ecosystem. As a leading vendor, we have been collaborating with SK hynix through many DDR generations, and are committed to providing high-performance, low-power memory interface solutions. Currently, Montage Technology offers a comprehensive portfolio of DDR5 logic devices – we are excited to further help SK hynix accelerate DDR5 market adoption,” said Geof Findley, VP of Sales and Business Development at Montage Technology.

“Compute-intensive workloads in the data center are accelerating the need for greater memory capacity and bandwidth,” said Chien-Hsin Lee, vice president and general manager, Integrated Circuits at Rambus. “DDR5 DRAM answers the call with higher data rates and new innovations that dramatically boost memory performance. Employing a new generation of memory interface chips, DDR5 RDIMMs and LRDIMMs will unleash the processing power of server platforms. We are pleased to partner with SK hynix to enable next-generation technology for the ecosystem and fulfill the growing demand for DDR5.”
