Samsung
Electronics, announced today that it is introducing the industry’s
first 8-gigabyte (GB) LPDDR4 (low power, double data rate 4) mobile DRAM
package, which is expected to greatly improve mobile user experiences,
especially for those using Ultra HD, large-screen devices. The 8GB
mobile DRAM package utilizes four of the newest 16 gigabit (Gb) LPDDR4
memory chips and advanced 10-nanometer (nm)-class* process technology.
“The
advent of our powerful 8GB mobile DRAM solution will enable more
capable next-generation, flagship mobile devices around the world,” said
Joo Sun Choi, executive vice president of Memory Sales and Marketing at
Samsung Electronics. “We will continue to provide advanced memory
solutions offering the highest values and leading-edge benefits to meet
the escalating needs of devices having dual camera, 4K UHD and VR
features.”
The
new 8GB LPDDR4 operates at up to 4,266 megabits per second (Mbps),
which is twice as fast as DDR4 DRAM for PCs working typically at 2,133
Mbps per pin. Assuming a 64 bit (x64) wide memory bus, this can be
viewed as transmitting over 34GBs of data per second.
While
many high-end ultra-slim note PCs use 8GB of DRAM currently, Samsung’s
new 8GB LPDDR4 package will help other next-generation mobile devices
take full advantage of its extremely high capacity. For example,
equipping tablets with 8GB of LPDDR4 will enable virtual machine
operation** and smoother 4K UHD video playback, popular features of many
premium PCs.
The
Samsung 8GB LPDDR4 DRAM provides much more efficient power consumption
thanks to its use of the latest 10nm-class process technology and
Samsung’s proprietary low-power circuit design. This circuit design
enables the memory chip to double the capacity of the company’s
20nm-class 4GB DRAM package, while consuming approximately the same
amount of power.
The
8GB LPDDR4 package has XYZ dimensions of under 15mm by 15mm by 1.0mm,
which satisfies space requirements of most new, ultra slim mobile
devices. Using a DRAM package thinner than 1.0mm enables stacking the
package together with UFS memory or a mobile application processor,
depending on device manufacturers’ preferences, which will allow further
space savings on the printed circuit board.
In
August last year, Samsung introduced the industry-first 20-nanometer
12Gb LPDDR4 DRAM. After only a 14-month development period, Samsung is
now introducing the first 10nm-class 16Gb LPDDR4 DRAM and this
single-package solution of 8GB LPDDR4 DRAM, which will speed up the
launch of next-generation mobile devices with even more advanced
performance.
Samsung
will continue to rapidly expand production of its DRAM products based
on 10nm-class process technology. The company has been manufacturing
10nm-class DRAM on a leading-edge fabrication line and plans to also use
the 10nm-process technology in other fabs in the near future, to meet
ever-increasing demands for advanced, high-density mobile DRAM.
