Samsung Electronics объявляет о начале массового производства 16-гигабитных микросхем LPDDR4X DRAM, изготавливаемых по 10-нанометровой технологии и предназначенных для установки в автомобилях.
Как отмечается в официальном пресс-релизе, что новая память демонстрирует высокую производительность и энергетическую эффективность, сохраняя работоспособность в экстремальных условиях при разбросе температур от -40°C до 125°C, соответствуя требованиям Automotive Grade 1.
Интерфейс LPDDR4X является самым быстрым для этого типа памяти, которая характеризуется пропускной способностью 4266 Мбит/с, что на 14% превосходит показатель памяти LPDDR4 DRAM плотностью 8 Гбит, выпускаемой по 20-нанометровой технологии. Превосходство новой памяти по энергетической эффективности достигает 30%.
Samsung Begins Mass Production of 10nm-class 16Gb LPDDR4X DRAM for Automobiles
The new 16Gb LPDDR4X DRAM features exceptionally high thermal endurance, with warranties for up to 125°C
Samsung Electronics, the world leader in advanced memory technology, today announced that it 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 significantly raising the thermal endurance level for automotive applications that often need to operate in extreme environments. The 10nm-class DRAM will also enable the industry’s fastest automotive DRAM-based LPDDR4X interface with the highest density.
“The 16Gb LPDDR4X DRAM is our most advanced automotive solution yet, offering global automakers outstanding reliability, endurance, speed, capacity and energy efficiency, ,” said Sewon Chun, senior vice president of memory marketing at Samsung Electronics. “Samsung will continue to closely collaborate with manufacturers developing diverse automotive systems, in delivering premium memory solutions anywhere.”
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. By more than satisfying the rigorous on-system thermal cycling tests of global auto manufacturers, the 16Gb LPDDR4X has enhanced its reliability for a wide variety of automotive applications in many of the world’s most challenging environments.
Adding to the degree of reliability under high temperatures, production at an advanced 10nm-class node is key to enabling the 16Gb LPDDR4X to deliver its leading-edge 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 advanced memory solution lineup for future automotive applications with the 10nm-class 16Gb LPDDR4X DRAM, commercially available in 12Gb, 16Gb, 24Gb and 32Gb capacities. While extending its 10nm-class DRAM offerings, 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.

Other than the smartphone and tablet, which device is also mobile and electronic? Cars are comprised of many important mechanical parts, many of which have been at their core for years now. But cars also can be considered as highly sophisticated electronic systems, hence semiconductors constituting an essential section.
As the graphics show below, semiconductor solutions are used in a wide array of automotive applications such as the camera and sensing system, dashboard, IVI (In-Vehicle Infotainment) system, ADAS (Advanced Driver Assistant System), autonomous driving central computing system and gateway. Semiconductors will be used even more extensively in the future, especially with the potential introduction of autonomous driving.
Samsung has been continuously cooperating with leading automobile manufacturers to make its semiconductor technologies available in the industry’s latest automobiles as well as next-generation cars. The company has participated in the Audi Progressive SemiConductor Program (PSCP) since 2015 with its advanced memory solutions and Exynos processors.
With its multiple operating system compatibility and support for multi-display, Samsung’s flagship Exynos processors enable powerful computing and graphics processing performance for today’s automobiles with highly graphical user interfaces. Along with its Exynos offerings, Samsung also plans to develop a wide array of logic IC solutions for upcoming automotive applications. Images sensors, working as the eyes of future vehicles, will have further improved frame rate and light sensitivity for thorough monitoring and sensing the driving environment.
When it comes to memory solutions, Samsung provides its high-performance, high-density LPDDR4 /LPDDR4X and GDDR6 DRAM lineups to address ever increasing demand for higher data bandwidth. For secure data storage, Samsung offers advanced eMMC and UFS solutions. All of these Samsung semiconductor solutions for automotive applications guarantee the highest performance levels among their kinds and are designed to endure tough environments inside the automobiles such as sudden temperature changes and continuous vibration.
Also offered by Samsung are LED components for interior and exterior lighting of automobiles such as cluster indicator lighting, headlamps and turn signal lamps. Based on upcoming technologies like pixel lighting, Samsung will be able to provide LED packages and modules that will enable more sophisticated and reliable lighting solutions.
