Samsung Develops Next-Gen RAM to Power 5G Phones


Samsung announced its latest milestone in future technology with its DRAM for use in 5G phones. The new LPDDR5 is meant to power mobile phones which will come with 5G technology as well as apps with Artificial Intelligence. In a press release published on July 17, Samsung declared about this new RAM which is based on 10-nanometer class 8-Gigabit LPDDR5 mobile chip, first of its kind in the industry. The RAM modules are already tested in its prototype stage and will go into mass production by the end of this year.

Samsung declares this RAM chip as a ‘major step’ towards finding the solution to the demand for low-power mobile memory, which is currently a major issue for future smartphones. The 8GB LPDDR5 achieved a data rate of 6,400 megabits per second, which is 1.5 times as fast as the current RAM (LPDDR4X, 4266 Mb/s) chips used in flagship mobile phones. As a result of this current data rate, LPDDR5 will be able to transfer 51.2 GB of data, which amounts to 14 full-HD video files, in one second.

The new DRAM chip will be available in two versions, one with 6,400 Mb/s and the other with 5,500 Mb/s. This means the RAM will be able to address a variety of mobile memory demands for future mobile devices.

The real deal with LPDDR5 lies in its power management skills. 5G technology and AI powered applications will need a lot more power than what is used by mobile phones today to function. According to Samsung, ‘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’. The chip will also ensure that mobile devices go into ‘deep sleep mode’ when not in use for a long time, this will cut the power consumption by half compared to what it is today. These low power features of LPDDR5 will reduce voltage usage by 30 percent, according to Samsung.

The new RAM chip is also designed to handle heavy applications, one that needs to manage Artificial Intelligence and Machine Learning algorithms at a faster pace than the current scenario. This chip will also be compatible with UHD resolutions of around 3,840 x 2,160 pixels.

What Samsung has developed already exists with phones like OnePlus 6 and Xiaomi Mi Mix 2, but LPDDR5 stands out for its low power efficiency and ability to handle future AI based applications. It is a highly optimized RAM chip meant to tackle 5G and AI, which will become more casual in a not too distant future.
