Samsung has commenced production of what it claims is the industry’s first 8GB low power double data rate 4 (LPDDR4) mobile DRAM, derived from its 20nm process technology.
Set to be ready by early next year, the new mobile DRAM can be deployed to develop LPDDR4 modules up to 4GB in size for smartphones and tablets.
Samsung Electronics Memory Sales and Marketing executive vice president Joo Sun Choi said: "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."
"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."
In addition to offering twice the performance and density compared to 4GB LPDDR3, the new 8Gb LPDDR4 boasts an I/O data rate of up to 3,200Mbps, which allows supporting UHD video recording and playback as well as continuous capturing of images of about 20mp resolution.
The new DRAM also boasts reduced power consumption while allowing high-frequency operations at low voltages for optimal power efficiency by implementing the new low-voltage swing-terminated logic (LVSTL) for its I/O signalling.
Based on the company’s 8GB AND 6GB LPDDR4 dies, the 2GB LPDDR4 and 3GB LPDDR4 DRAM are already being offered this month, while the 4GB LPDDR4 packages set to be ready by early next year.
