Samsung Electronics, has announced industry’s first 8GB RAM that uses 16GB LPDDR4 mobile DRAM, based on the 10-nanometer (nm) class process technology. More amount of RAM will be useful for devices with dual cameras, 4K UHD recording and VR features.
The new 8GB LPDDR4 operates at up to 4,266 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.
The company has already started mass producing 6GB / 12-Gb LPDDR4 mobile DRAM based 20-nanometer (nm) process technology at the end of 2015.
Samsung’s 8GB LPDDR4 Key Features
- Fabricated on 10-nanometer (nm) class process technology
- 4 x 16 gigabit (Gb) LPDDR4 memory chips
- Data transfer rate of 4,266 megabits per second (Mbps) per pin, 30% faster than 20nm-based 8Gb LPDDR4
- Twice as fast as DDR4 DRAM for PCs, while consuming 20% less energy
- 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, further space savings on the printed circuit board
Samsung said that 8GB LPDDR4 RAM is expected in next-generation flagship mobile devices. We are hoping to have it in the Galaxy S8 next year. As per samsung report, the company 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.
