The industry's first 8Gb LPDDR5 DRAM from Samsung Electrnics

Samsung Electronics has successfully developed the industry’s first 10-nanometer (nm) class 8-gigabit (Gb) LPDDR5 DRAM.

Since bringing the first 8Gb LPDDR4 to mass production in 2014, Samsung has been setting the stage to transition to the LPDDR5 standard for use in upcoming 5G and Artificial Intelligence (AI)-powered mobile applications.

The newly-developed 8Gb LPDDR5 is the latest addition to Samsung’s premium DRAM lineup, which includes 10nm-class 16Gb GDDR6 DRAM (in volume production since December 2017) and 16Gb DDR5 DRAM (developed in February).

“This development of 8Gb LPDDR5 represents a major step forward for low-power mobile memory solutions,” said Jinman Han, senior vice president of Memory Product Planning & Application Engineering at Samsung Electronics, on July 16. “We will continue to expand our next-generation 10nm-class DRAM lineup as we accelerate the move toward greater use of premium memory across the global landscape.”

The 8Gb LPDDR5 boasts a data rate of up to 6,400 megabits per second (Mb/s), which is 1.5 times as fast as the mobile DRAM chips used in current flagship mobile devices (LPDDR4X, 4266Mb/s). With the increased transfer rate, the new LPDDR5 can send 51.2 gigabytes (GB) of data, or approximately 14 full-HD video files (3.7GB each), in a second.

The 10nm-class LPDDR5 DRAM will be available in two bandwidths – 6,400Mb/s at a 1.1 operating voltage (V) and 5,500Mb/s at 1.05V – making it the most versatile mobile memory solution for next-generation smartphones and automotive systems.

This performance advancement has been made possible through several architectural enhancements. By doubling the number of memory “banks” – subdivisions within a DRAM cell – from eight to 16, the new memory can attain a much higher speed while reducing power consumption. The 8Gb LPDDR5 also makes use of a highly advanced, speed-optimized circuit architecture that verifies and ensures the chip’s ultra-high-speed performance.

Based on its industry-leading bandwidth and power efficiency, the LPDDR5 will be able to power AI and machine learning applications, and will be UHD-compatible for mobile devices worldwide.
