Samsung introduces the industry’s first 8GB LPDDR4 mobile DRAM package

Samsung has today announced the industry’s first 8-gigabyte (GB) LPDDR4 mobile DRAM package, which will greatly improve mobile user experiences on larger devices with an Ultra HD display. The 8GB DRAM package is constructed using four of the newest 16 -gigabit (Gb) LPDDR4 chips and the firm’s advanced 10nm-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 VP of Memory Sales at Samsung. “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.”

As you’d expect, the new 8GB LPDDR4 module is significantly faster than DDR4 DRAM chip for PCs. In fact, it’s actually twice as fast, operating at speeds of up to 4,266 megabits per second (Mbps). If it assumes a 64 bit (x64) wide memory bus,  it can be used to transmit over 34GB of data per second, which is pretty astonishing for such a tiny component.

The 8GB LPDDR4 package won’t only be built into smartphones, though. It will also make its way to high-end tablets, which will enable them to smoothly run virtual machines and allow for a more fluid 4K UHD video playback experience. The 10nm-class process technology and Samsung’s low-power circuit design allows for longer battery life, too.

With regards to dimensions, the chip measures in at under 15mm by 15mm by 1.0mm, which satisfies space requirements of most new, ultra-slim mobile devices. Seeing as the module is thinner than 1.0mm, manufacturers will be able to stack it together with UFS memory or a mobile application processor, which allows for further space savings on the PCB.

I hope this makes it’s way into the S8 and Note 8.


I doubt that Samsung will jump from 4GB to 8GB but rather to 6GB with the S8, maybe with the Note 8 (or however that device will be called, if there is more than 1 flagship next year that is) or S9 to 8GB.
