Samsung 2nd generation 10-nano level mobile DRAM mass-production begins

While earlier this month Samsung announced its new 8Gb LPDDR5 DRAM chips, the South Korean manufacturer made another memory-related announcement. Samsung has begun the mass production of the second-generation, 10-nanometer-class (1y-nm) LPDDR4X (Low Power, Double Data Rate, 4X) DRAM.

These chips will be more efficient and battery friendly. They’re destiuned to be used in premium smartphones and other mobile applications. Compared to the current chips residing in smartphones, the second-generation chips reduce power consumption by 10 percent, while maintaining the same data rate of 4,266 megabits per second (Mb/s).

Samsung also announced that it achieved an 8GB LPDDR4X mobile DRAM package by combining four of the 10nm-class 16Gb LPDDR4X DRAM chips (16Gb=2GB). This package is capable of data rates of 34.1GB per second, while being 20 percent thinner compared to the first-generation. This will allow OEMs to further slim down the form factor of their mobile devices.

Samsung Electronics, the world leader in advanced memory technology, today announced that it has begun mass producing the industry’s first 2nd-generation of 10-nanometer-class* (1y-nm), LPDDR4X (Low Power, Double Data Rate, 4X) DRAM to improve the efficiency and lower the battery drain of today’s premium smartphones and other mobile applications.

Compared to the mobile DRAM memory chips most used in current flagship mobile devices (1x-nm 16Gb LPDDR4X), the 2nd– generation LPDDR4X DRAM features up to a 10 percent power reduction while maintaining the same data rate of 4,266 megabits per second (Mb/s).

“The advent of 10nm-class mobile DRAM will enable significantly enhanced solutions for next-generation, flagship mobile devices that should first hit the market late this year or the first part of 2019.” said Sewon Chun, senior vice president of Memory Sales & Marketing at Samsung Electronics. “We will continue to grow our premium DRAM lineup to lead the ‘high-performance, high capacity, and low power’ memory segment to meet the market demand and strengthen our business competitiveness.”

Samsung will be expanding its premium DRAM lineup that is based on the 1y-nm process by more than 70 percent. This initiative began with mass producing the first 10nm-class 8Gb DDR4 server DRAM last November and continues with this 16Gb LPDDR4X mobile memory chip only eight months later.

Samsung said that it has created an 8GB LPDDR4X mobile DRAM package by combining four of the 10nm-class 16Gb LPDDR4X DRAM chips (16Gb=2GB). This four-channel package can realize a data rate of 34.1GB per second and its thickness has been reduced more than 20 percent from the 1st-gen package, enabling OEMs to design slimmer yet more effective mobile devices.

With its LPDDR4X advancements, Samsung will be rapidly expanding its share of mobile DRAM in the market by providing a variety of high-capacity products, including 4GB, 6GB and 8GB LPDDR4X packages.

In line with its roll-out of 10nm-class LPDDR4X, Samsung has started operating a new DRAM production line in Pyeongtaek, Korea, to assure a stable supply of all mobile DRAM chips, in response to the increasing demand.

*10nm-class denotes a process technology node somewhere between 10 and 19 nanometers.
