The RAM market is going through a difficult period, with rising prices and supply shortages. However, this crisis is also serving as a springboard for Chinese manufacturers to accelerate their plans and make a significant leap forward. CXMT (ChangXin Memory Technologies) has been the first to make a move with the new generation of LPDDR6 memory, an advance that could shift the balance of power in the semiconductor industry.
In the midst of the storm, the Chinese company has confirmed that it has already begun mass production of its LPDDR6 chips, a milestone that puts it ahead of giants like Samsung, SK Hynix, and Micron, which still don't have a commercially ready product. The first customer will be Xiaomi, which will integrate this memory into its upcoming foldable phone, the Xiaomi 18 Fold, scheduled for release this September. This is certainly no coincidence: the alliance between the two companies aims to make a strong statement in the premium segment.
CXMT begins mass production of LPDDR6
The news arrived in two stages: first, CXMT itself announced on its Weibo account that it was already shipping the first units to Xiaomi; then, it officially confirmed the start of mass production. These chips achieve a transfer speed of up to 12,8 Gbps per pin , with a base rate of 10,7 Gbps, representing a significant improvement over the previous LPDDR5X generation, which required pushing the modules to their limits to reach that maximum. Each chip has a capacity of 16 Gb (equivalent to 2 GB) and uses a POP package with 1.295 pins, a design intended to optimize power consumption and space in mobile devices.
This move puts CXMT in a privileged position, as it becomes the first company to offer LPDDR6 commercially. Competitors like SK Hynix have already shown prototypes capable of reaching 14,4 Gbps, but have not yet begun mass production. This early advantage could be key, especially at a time when demand for high-performance memory is skyrocketing. Analysts believe this early start could help moderate DRAM prices , which have been rising for months due to shortages.
Xiaomi 18 Fold, the first device with LPDDR6
Xiaomi's foldable phone will be the first to feature this technology. As confirmed by both companies, the Xiaomi 18 Fold will incorporate CXMT's LPDDR6 chips in its main configuration. The launch is set for September, and it is expected to be one of the most expensive and advanced phones of the year. However, initial production will be quite limited. Estimates suggest that no more than 300.000 units of the foldable phone will be produced, a number determined by both the complexity of the device itself and the limitations CXMT faces in large-scale manufacturing.
The exclusivity is twofold: for now, no other manufacturer has confirmed that it will use this memory, making the Xiaomi 18 Fold the only device with LPDDR6 in the short term. This selective launch strategy allows Xiaomi to differentiate itself from the competition, although it also means that the general public won't be able to enjoy the advantages of this memory until production is scaled up. The brand has invested heavily in this component instead of using the previous generation, aware that the extra performance justifies the higher price.
Market restrictions and competition
Behind the production limitations lies, once again, the shadow of US sanctions. CXMT cannot acquire state-of-the-art lithographic machinery, so it is forced to use older DUV (Deep Ultraviolet) equipment and resort to complex multi-pattering techniques. This increases the cost of the process and reduces output, which explains why they can currently only manufacture a small volume. Even so, the company has demonstrated its ability to innovate within these restrictions and is working on a lawsuit against the US Department of Defense to be removed from the blacklist that links it to the Chinese military.
Meanwhile, Samsung and SK Hynix still don't have an LPDDR6 ready for sale. They've announced developments, but haven't started mass production. This gives CXMT a window of opportunity that could be decisive if it manages to scale up its manufacturing. Experts agree that CXMT's ability to keep pace and increase production will be the real test, since when the big players enter the market, they'll be able to manufacture millions of units in a short time. For now, the Chinese company has made a strong statement, and everything points to the memory sector undergoing a cyclical shift that could benefit consumers in the medium term.
In short, CXMT's launch of LPDDR6 production is a milestone that affects not only Xiaomi but the entire tech ecosystem. The entry of a new player with cutting-edge technology, even with limitations, introduces competition that can help level the playing field and accelerate innovation. It will be important to closely monitor how production progresses and whether Samsung or SK Hynix react in time to avoid falling behind. What is clear is that, for the first time in years, a Chinese manufacturer is setting the pace for the launch of next-generation RAM.
