Samsung Electronics started volume production of 8 Gb low power double data rate 4 (LPDDR4) mobile DRAM using 20-nanometer (nm) process technology. LPDDR4 are used in latest smart phones and mobile devices for higher capacity, speed and low power.
“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.”
8Gb LPDDR4 support UHD video recording and playback and continuous shooting of high-resolution images with over 20 megapixels With I/O data rate of up to 3,200 megabits per second (Mbps).
The LPDDR4 operates at 1.1V and save up to 40 percent of power compared to a 4Gb LPDDR3-based 2GB package, due to low operating voltages and faster processing.
By adopting new proprietary low-voltage swing-terminated logic (LVSTL) for its I/O signaling, Samsung said it has also further reduced the new LPDDR4 chip’s power consumption while enabling high-frequency operations at low voltages for optimal power efficiency.
