"This development of 8Gb LPDDR5 represents a major step forward for low-power mobile memory solutions", said Jinman Han, a senior vice president at Samsung.

With the nipper data rate, Samsung is aiming the 8Gb LPDDR5 memory to become a standard for use in mobile phones that tap into 5G connectivity and have AI capabilities - think the Google Assistant and the AI smarts in the Huawei P20 Pro and Pixel 2 phones.

Samsung said the chip is capable of transmitting 14 full-HD quality movies of 51.2 gigabytes (Gb) in a second.

Samsung on Monday unveiled a new memory chip for mobile devices that promises 50 percent speed improvements and 30 percent better battery life.

Samsung officially announced its 8GB LPDDR5 DRAM chip for smartphones today. The memory is embedded with advanced circuit architecture to deliver ultra-high-speed performance. According to the company, LPDDR5 standard will be used in forthcoming next-generation devices and supports 5G and AI-powered mobile apps. The new DRAM comes in two bandwidths, one in 6,400Mb/s at 1.1 operating voltage (V) and another in 5,500Mb/s at 1.05V. Put another way, the company sees it being used in "next-generation smartphones and automotive systems".

With this announcement, Samsung also highlighted the key achievements of the 8GB LPDDR5 DRAM. Additionally, the chip has been configured to avoid overwriting cells with "0" values, thereby avoiding wasting electricity on reiterating an existing value.

The new DRAM also has a "deep sleep mode" that cuts the power usage to approximately half the "idle mode" of current generation LPDDR4X DRAM.

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. Its mass production is expected to start soon in Samsung's manufacturing facility in Pyeongtaek, Korea. Nearly all high-end phones, mobile devices, and even portable PCs these days use LPDDR4X or even just LPDDR4.
