8Gb LPDDR4 started mbad production in 2014. 8Gb LPDDR5 Combines Samsung's premium DRAM line, which includes a 10nm 16Gb GDDR6 DRAM (in volume since December 2017) and a 16Gb DDR5 DRAM (developed in February). The development of LPDDR5 8Gb represents a major breakthrough for low-power mobile memory solutions, "says Jinman Han of Samsung
The LPDDR5 8Gb has a data rate of up to 6,400 Mb / s, or 1, 5 times faster than mobile DRAM chips used in today's flagship mobile devices (LPDDR4X, 4266Mb / s).
With increased transfer rate, the new LPDDR5 can send 51.2 gigabytes (GB) of data, or about 14 full HD video files (3.7 GB each)
LPDDR5 10nm DRAM will be available in two bandwidths – 6,400Mb / s at an operating voltage of 1.1 (V) and 5,500Mb / s at 1,05V,
. several architectural improvements. By doubling the number of "banks" of memory – subdivisions in a DRAM cell – from eight to 16, the new memory can reach a much higher speed while reducing power consumption. The LPDDR5 8Gb also uses a very advanced and speed optimized circuit architecture that verifies and guarantees the ultra-fast performance of the chip.
In order to maximize energy savings, the 10nm LPDDR5 was designed to reduce its voltage according to the operating speed of the corresponding application processor, in active mode.
It has also been configured to avoid crushing cells with values of 0.
In addition, the new LPDDR5 chip will offer a "deep sleep". "mode", which reduces power consumption to about half of the "inactive mode" of the current LPDDR4X DRAM.
With these low-power features, the LPDDR5 8Gb DRAM delivers up to 30% power consumption savings, maximizing its bandwidth and energy efficiency, allowing LPDDR5 to power AI applications. and machine learning, and will be compatible with UHD technology for device performance and will extend the battery life of smartphones.
Samsung, with the world's leading chip vendors, has completed the functional testing and validation of a 8GB LPDDR5 DRAM memory prototype, consisting of eight 8GB LPDDR5 chips.
Leveraging Advanced Manufacturing Infrastructure Its latest line in Pyeongtaek, Korea, Samsung plans to begin mbad production of its new generation DRAMs (LPDDR5, DDR5 and GDDR6) in line with global customer demands .
