First 8Gb Mobile DRAM
Samsung Electronics announced 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 in October. The 8Gb mobile DRAM package utilizes four of the newest 16 Gb LPDDR4 memory chips.
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 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.
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 eUFS memory or a mobile application processor, which will allow the development of a thinner smartphone.
