In late August 2026, Chinese memory chipmaker ChangXin Memory Technologies (CXMT) announced it will supply its latest LPDDR6 Dynamic Random-Access Memory chips for Xiaomi’s upcoming flagship folding phone, the 18 Fold. The hardware partnership arrives just as CXMT scales mass production of LPDDR6 and debuts following a blockbuster public share listing on the Shanghai Stock Exchange’s STAR Market.
Mass Production and Mobile Integration
CXMT has officially started mass production of LPDDR6, reaching the milestone less than a year after rolling out the previous generation of LPDDR5 chips, according to statements posted on Weibo. Xiaomi confirmed via its official social media channels that the upcoming 18 Fold will incorporate these advanced memory modules when it releases in September.
The integration of LPDDR6 aligns with Xiaomi’s broader hardware architecture updates. According to company disclosures, the new foldable device is expected to leverage a new version of Xiaomi’s in-house 3-nanometre handset processor, the Xring O3, which would support LPDDR6.
Beyond mobile handsets, CXMT announced it has shipped samples of its LPDDR6 chips to customers across multiple verticals, targeting servers and smart cars. As noted by GSMArena, the Xring O3 processor architecture represents at least a two-generations leap in power efficiency for Xiaomi’s proprietary silicon efforts.
Market Realities and Financial Surge
The supply agreement follows a historic financial and market milestone for the Hefei-based semiconductor firm. In its first earnings release since going public, CXMT reported a dramatic turnaround to profit for the first half of 2026, with revenue spiking 874% year-on-year to reach 150.3 billion yuan ($22.36 billion), according to data reported by Reuters.
This commercial expansion follows CXMT’s massive initial public offering on the Shanghai Stock Exchange’s STAR Market in July 2026. During its market debut, CXMT shares surged 472%, hitting a market capitalization of about 3.3 trillion yuan (approximately €415 billion). While the listing ranks as mainland China’s second-largest IPO after the Agricultural Bank of China’s 2010 dual listing—CXMT’s overall valuation remains below established global memory giants such as Samsung Electronics, SK Hynix, and Micron Technology.
Geopolitical Pressures and Export Controls
Operating at the center of China’s domestic technology push, CXMT has grown rapidly while navigating strict US-led export controls. According to Kyle Chan, a fellow at the Brookings Institution, CXMT plays a critical role in China’s artificial intelligence and semiconductor self-sufficiency initiatives, particularly as US restrictions block the import of advanced High-Bandwidth Memory (HBM) chips.
Counterpoint Research data indicates that CXMT captured roughly 8% of the global DRAM market in 2025, and approximately 9% of global shipments in the first three months of this year, placing it fourth globally behind Samsung, SK Hynix, and Micron. Industry analysts project that CXMT’s market share will reach about 11% by 2028—and the research firm estimated it will likely need at least a 15% global market share to be competitive in the long term. However, analysts note that supply chain bottlenecks and strict limitations on access to the world’s best chipmaking tools continue to force heavy reliance on domestic equipment makers.
Legal and political headwinds are also mounting. Alongside its commercial announcements, CXMT filed a lawsuit against the United States Pentagon following its designation on a military-linked restricted list, as reported by Reuters. Concurrently, some US lawmakers have urged the administration of President Donald Trump to block American firms from purchasing CXMT memory components, citing ongoing national and economic security concerns.
