Mass production planned for next year

South Korea’s Samsung Electronics announced on Dec. 21 that it had developed a 16-gigabit (Gb) DDR5 DRAM built using the industry’s first 12-nm class process technology.

Samsung plans to start mass production with the new technology next year. The Seoul-based tech giant said that the previous best technology had been its own 14-nm class.

A nanometer is one-billionth of a meter. The width of human hair is typically between 80,000 and 100,000 nanometers.

“Our 12nm-range DRAM will be a key enabler in driving market-wide adoption of DDR5 DRAM,” Samsung Executive Vice President Lee Joo-young said in a statement.

“With exceptional performance and power efficiency, we expect our new DRAM to serve as the foundation for more sustainable operations in areas such as next-generation computing, data centers, and AI-driven systems.”

Samsung also said that the technology had been designed to be compatible with AMD’s Zen platforms.

“Innovation often requires close collaboration with industry partners to push the bounds of technology,” AMD Senior Vice President Joe Macri said.

Experts pointed out that Samsung’s achievements would play a huge role in the three-way rivalry of major chipmakers.

“Global chipmakers compete very hard to reduce the nanometer of their technology for better yield rates and lower power consumption,” Prof. Han Tae-hee at Sungkyunkwan University said.

“The 12nm DRAM would boost Samsung Electronics in the global rivalry with South Korea’s SK hynix and Micron Technology of the United States.”

As the iconic affiliate of Samsung Group, Samsung Electronics is the world’s largest manufacturer of memory chips, smartphones, and flat-panel displays.
