Samsung has today officially announced the introduction of what is said to be the industry’s first 8GB LPDDR4 (low power, double data rate 4) DRAM package for mobile devices. According to the report, the 8GB mobile DRAM package uses four of its latest 16GB LPDDR4 memory chips and is manufactured using advanced 10nm-class process technology.
The 8GB LPDDR4 DRAM comes in as a powerful mobile DRAM solution which the company says will enable more capable next-generation, flagship mobile devices around the world and is suited to meet the escalating needs of devices having dual camera, 4K UHD and VR features.
Continuing, the company disclosed 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. Already, there are a number of high-end ultra-slim note PCs using 8GB of DRAM currently but 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.
In addition, 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.
In terms of dimension, the 8GB LPDDR4 package comes in under 15mm x 15mm x 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 and now after only 14 months in development, the Korean tech giant is introducing the first 10nm-class single-package solution of 8GB LPDDR4 DRAM which is expected to speed up the launch of next-generation mobile devices and tablets with even more advanced performance.
