Micron has announced that it has commenced mass production of the industry's highest capacity monolithic 12 Gb LPDDR4x DRAM for mobile devices. The latest LPDDR4x chips aim to offer double the memory capacity while consuming lesser power and still retaining the same footprint as the previous generation.

Micron has started mass producing its LPDDR4x DRAM chips fabricated using the 1Y-nm (10 nm) process. Micron says that its new chips are the industry's first high-capacity monolithic 12 Gb mobile DRAM modules and they are capable of up to 10% lesser power consumption than the previous generation for similar data rates at up to 4,266 Mbps. 

Micron is not alone in the LPDDR4x market, though. SK Hynix introduced 16 Gb LPDDR4x chips back at the start of 2017. Micron's 12 Gb capacity is lower, but it allows the company to offer lower-cost quad-die solutions than the competition. LPDDR4x has an output voltage of just 0.6 V compared to 1.1 V in LPDDR4, which translates to increased power efficiency for mobile devices. Micron says that these higher DRAM capacities are required to support the increasing use of AI and AR in mobile devices. With the imminent arrival of 5G handsets next year, having denser memory with higher data rates will help in faster real-time processing of data. 

The memory semiconductor market is controlled mainly by Samsung, SK Hynix, and Micron. In fact, Samsung had already announced plans for bringing LPDDR5 DRAM to market by H2 2018 but that date has now been pushed to 2020 with both Samsung and Micron expected to kick off LPDDR5 production sometime next year. Till then, LPDDR4x should provide the needed data rates and power efficiencies for the upcoming crop of mobile devices.

Though a cell and molecular biologist by training, I have been drawn towards computers from a very young age ever since I got my first PC in 1998. My passion for technology grew quite exponentially with the times, and it has been an incredible experience from being a much solicited source for tech advice and troubleshooting among family and friends to joining Notebookcheck in 2017 as a professional tech journalist. Now, I am a Lead Editor at Notebookcheck covering news and reviews encompassing a wide gamut of the technology landscape for Indian and global audiences. When I am not hunting for the next big story or taking complex measurements for reviews, you can find me unwinding to a nice read, listening to some soulful music, or trying out a new game.
