Samsung has started mass production of industry’s first 8 gigabit (Gb) low power double data rate 4 (LPDDR4) mobile DRAM, which is based on leading edge 20-nanometer process technology. Samsung says that the new 8Gb ultra-fast mobile memory will open doors to the era of 4GB mobile DRAM for smartphones.

“By initiating production of the 20nm 8Gb LPDDR4, which is even faster than the DRAM for PCs and servers and consumes much less energy, we are contributing to the timely launch of UHD, large-screen flagship mobile devices,” said Joo Sun Choi, Executive Vice President of Memory Sales and Marketing at Samsung Electronics. “As this major advancement in mobile memory demonstrates, we will continue to closely collaborate with global mobile device manufacturers to optimize DRAM solutions, making them suitable for next-generation mobile OS environments.”

Compared to current generation 20nm 4Gb LPDDR3 DRAM the new 8Gb LPDDR4 DRAM will offer twice the performance, while decreasing power consumption by 40 percent for a 2GB package.

Due to an I/O data rate of up to 3,200 megabits per second (Mbps), which is two times faster than a typical DDR3 DRAM used in PCs, the new 8Gb LPDDR4 can support UHD video recording and playback and continuous shooting of high-resolution images with over 20 megapixels.

Samsung started providing 2GB LPDDR4 and 3GB LPDDR4 DRAM packages this month based on 8Gb and 6Gb LPDDR4 dies, respectively, and will provide 4GB LPDDR4 packages in early 2015.
