Samsung Electronics has begun mass producing 10-nanometer (nm)-class 16-gigabit (Gb) LPDDR4X DRAM for automobiles.
The latest LPDDR4X features high performance and energy efficiency while raising the thermal endurance level for automotive applications that often need to operate in extreme environments. The
Moving a step beyond its 20nm-class 'Automotive Grade 2' DRAM, which can withstand temperatures from -40°C to 105°C, Samsung's 16Gb LPDDR4X is Automotive Grade 1-compliant, raising the high-end threshold to 125°C.
Adding to the degree of reliability under high temperatures, production at a 10nm-class node is key to enabling the 16Gb LPDDR4X to deliver its performance and power efficiency. Even in environments with extremely high temperatures of up to 125°C, its data processing speed comes in at 4,266 megabits per second (Mbps), a 14 percent increase from the 8Gb LPDDR4 DRAM that is based on 20nm process technology, and the new memory also registers a 30 percent increase in power efficiency.
Along with a 256 gigabyte (GB) embedded Universal Flash Storage (eUFS) drive announced in February, Samsung has expanded its memory solution lineup for future automotive applications with the 10nm-class 16Gb LPDDR4X DRAM, commercially available in 12Gb, 16Gb, 24Gb and 32Gb capacities. The company also plans on bolstering technology partnerships for automotive solutions that include vision ADAS (Advanced Driver Assistance Systems), autonomous driving, infotainment systems and gateways.
