Development of 1z Nano 8Gb DDR4 DRAM Completed
| Leading the Expansion of the Next-Generation DDR5/LPDDR5 Market
Mass production of 1z nanometer DRAM lineup in 2019

Samsung Electronics announced on the 21st that it has developed the '3rd generation 10nm-class (1z) 8Gb DDR4 DRAM'.
Samsung Electronics has once again overcome the limitations of fine process technology by developing the third-generation 10nm-class (1z) 8Gb DDR4 DRAM, just 16 months after mass-producing the second-generation 10nm-class (1y) DRAM.

The third-generation 10nm-class (1z) DRAM has improved productivity by more than 20% compared to the existing 10nm-class (1y) DRAM without using ultra-expensive EUV equipment, and power efficiency has also improved due to the increased speed.

Samsung Electronics has also completed approval in all evaluation items of global CPU manufacturers for its 3rd generation 10nm-class (1z) DRAM-based DDR4 modules for PCs, enabling it to fully expand its demand from global IT customers.

Samsung Electronics will begin mass production of the third-generation 10nm-class (1z) DRAM in the second half of 2019, and in 2020, it will begin supplying next-generation DRAM (DDR5, LPDDR5, etc.) with improved performance and capacity, thereby providing premium products based on cutting-edge processes. We plan to further strengthen our leadership in memory technology.

Samsung Electronics also plans to actively collaborate with major global customers from the next-generation system development stage to quickly transition the global market to the next-generation lineup.

“We have been able to launch the next-generation lineup of ultra-high-speed and ultra-low-power products at the right time through the development of innovative DRAM technology that overcomes the limitations of microfabrication,” said Lee Jung-bae, Vice President of the DRAM Development Lab at Samsung Electronics’ Memory Business Division. “We will continue to expand our premium DRAM lineup to contribute to the timely launch of next-generation systems for global customers and the rapid growth of the premium memory market.”

Meanwhile, Samsung Electronics is continuously expanding the production of its flagship products at its latest DRAM line in Pyeongtaek to meet the supply demands of its global IT customers. By establishing a stable mass production system in Pyeongtaek to reflect the growing demand for next-generation premium DRAM in 2020, the company plans to strengthen its competitiveness in the ultra-gap business.
