Your next phone will likely have more RAM: Samsung announces 8Gb LPDDR5 DRAM
Whether more RAM in your future smartphone is acually needed or not is up for debate. We’ve seen phones jump from one gig to two, four, and more recently, six. Overkill was the buzz word for each and every one of these upgrades. Eight gigs might be around the corner, as Samsung just announced its new 8Gb LPDDR5 DRAM chips.
5G and AI-powered Mobile Applications seem to be the reason behind its existence. While we might be able to debate the amount of memory used inside devices, we can all agree on the fact that the speed of these components is vital. The faster the better!
These new chips are capable of data rates of up to 6,400Mb/s. That’s 1.5 times faster than the LPDDR4X chips used in current flagship phones (at 4,266Mb/s). To put things in perspective, it takes them a second to transfer 51.2GB of data, says Samsung. That’s at a voltage of 1.1V; lowering the voltage to 1.05V will “slow” them down to 5,500Mb/s. That’s fast! How about some faster storage (ROM) chips?
With the upcoming adoption of 5G, and the increasing penetration of AI, more memory at faster speeds will become a necessity. And, if you are among those who think that much memory inside a phone is overkill, there are plenty of other usage scenarios, like automotive systems, or other connected devices.
With that, let us know in the comments? What do you prefer: faster memory, or more memory? Yes, faster and more is also a valid choice.
The newly-developed 8Gb LPDDR5 is the latest addition to Samsung’s premium DRAM lineup, which includes 10nm-class 16Gb GDDR6 DRAM (in volume production since December 2017) and 16Gb DDR5 DRAM (developed in February).
“This development of 8Gb LPDDR5 represents a major step forward for low-power mobile memory solutions,” said Jinman Han, senior vice president of Memory Product Planning & Application Engineering at Samsung Electronics. “We will continue to expand our next-generation 10nm-class DRAM lineup as we accelerate the move toward greater use of premium memory across the global landscape.”
The 8Gb LPDDR5 boasts a data rate of up to 6,400 megabits per second (Mb/s), which is 1.5 times as fast as the mobile DRAM chips used in current flagship mobile devices (LPDDR4X, 4266Mb/s). With the increased transfer rate, the new LPDDR5 can send 51.2 gigabytes (GB) of data, or approximately 14 full-HD video files (3.7GB each), in a second.
The 10nm-class LPDDR5 DRAM will be available in two bandwidths – 6,400Mb/s at a 1.1 operating voltage (V) and 5,500Mb/s at 1.05V – making it the most versatile mobile memory solution for next-generation smartphones and automotive systems. This performance advancement has been made possible through several architectural enhancements. By doubling the number of memory “banks” – subdivisions within a DRAM cell – from eight to 16, the new memory can attain a much higher speed while reducing power consumption. The 8Gb LPDDR5 also makes use of a highly advanced, speed-optimized circuit architecture that verifies and ensures the chip’s ultra-high-speed performance.
To maximize power savings, the 10nm-class LPDDR5 has been engineered to lower its voltage in accordance with the operating speed of the corresponding application processor, when in active mode. It also has been configured to avoid overwriting cells with ‘0’ values. In addition, the new LPDDR5 chip will offer a ‘deep sleep mode’, which cuts the power usage to approximately half the ‘idle mode’ of the current LPDDR4X DRAM. Thanks to these low-power features, the 8Gb LPDDR5 DRAM will deliver power consumption reductions of up to 30 percent, maximizing mobile device performance and extending the battery life of smartphones.
Based on its industry-leading bandwidth and power efficiency, the LPDDR5 will be able to power AI and machine learning applications, and will be UHD-compatible for mobile devices worldwide.
Samsung, together with leading global chip vendors, has completed functional testing and validation of a prototype 8GB LPDDR5 DRAM package, which is comprised of eight 8Gb LPDDR5 chips. Leveraging the cutting-edge manufacturing infrastructure at its latest line in Pyeongtaek, Korea, Samsung plans to begin mass production of its next-generation DRAM lineups (LPDDR5, DDR5 and GDDR6) in line with the demands of global customers.
