Samsung Electronics Co., Ltd., the world leader in advanced memory technology, on Thursday announced that it has developed the industry’s first 512GB DDR5 (Double Data Rate 5) module based on High-K Metal Gate (HKMG) process technology.
The new DDR5 module has been designed to orchestrate the most extreme compute-hungry, high-bandwidth workloads in supercomputing, artificial intelligence (AI) and machine learning (ML), as well as data analytics applications.
Samsung’s new DDR5 memory module is claimed to deliver more than twice the performance of DDR4 at up to 7,200 megabits per second (Mbps). It utilizes the highly advanced HKMG technology that has been traditionally used in logic semiconductors.
Due to the continued scaling down of DRAM (Dynamic Random Access Memory) structures, the insulation layer has thinned, leading to a higher leakage current. By replacing the insulator with HKMG material, Samsung’s DDR5 will be able to reduce the leakage and reach new heights in performance. This new memory will also use approximately 13% less power, making it especially suitable for datacenters where energy efficiency is becoming increasingly critical.
The new DDR5 modules also use silicon via (TSV) technology to stack eight layers of 16Gb DRAM chips to offer the largest capacity of 512GB. TSV was first utilized in DRAM in 2014 when Samsung introduced server modules with capacities up to 256GB.
The HKMG process was adopted in Samsung’s GDDR6 memory in 2018 for the first time in the industry before it was expanded to DDR5 memory. By expanding its use in DDR5, Samsung is further solidifying its leadership in next-generation DRAM technology.
“Samsung is the only semiconductor company with logic and memory capabilities and the expertise to incorporate HKMG cutting-edge logic technology into memory product development. By bringing this type of process innovation to DRAM manufacturing, we are able to offer our customers high-performance, yet energy-efficient memory solutions to power the computers needed for medical research, financial markets, autonomous driving, smart cities and beyond,” said Young-Soo Sohn, Vice President of the DRAM Memory Planning/Enabling Group at Samsung Electronics.
“As the amount of data to be moved, stored and processed increases exponentially, the transition to DDR5 comes at a critical inflection point for cloud datacenters, networks, and edge deployments. Intel’s engineering teams closely partner with memory leaders like Samsung to deliver fast, power-efficient DDR5 memory that is performance-optimized and compatible with our upcoming Intel Xeon Scalable processors, code-named Sapphire Rapids,” said Carolyn Duran, Vice President and GM of Memory and IO Technology at Intel.
Currently, Samsung is sampling different variations of its DDR5 memory product family to customers for verification. Once it receives certification for final usage, it is likely to be available in the market in the latter half of 2021.
