CXMT (ChangXin Memory Technologies) is the biggest manufacturer of DRAM in China and the fourth largest globally after Samsung, SK Hynix, and Micron. Its share of global DRAM revenue was about 10% in Q2 2026, up from less than 1% in 2023 and not predicted by analysts before 2028.
Its DDR5 and LPDDR memory chips are already available in phones and laptops. Considering the perspective of a buyer of memory, it provides one of the possible options to get the chip as a backup, although it is not cheap and has certain constraints as imposed by US regulations on the use of its chip.
Understanding CXMT
CXMT was founded in May 2016 in Hefei, Anhui province, by chairman Zhu Yiming. Investors linked to the Hefei government hold about 37% of the company, and China's national chip fund is also a major shareholder, according to company records.
It runs 12 inch DRAM fabs in Hefei and Beijing and is building an HBM packaging site in Shanghai. On July 27, 2026, CXMT listed on Shanghai's STAR Market under code 688825, raising about ¥57.9 billion, roughly $8.6 billion. Its shares rose close to 500% on the first day.
CXMT Market Share in 2026
CXMT has grown faster than any forecast expected. Here is the Q2 2026 DRAM revenue split, based on Counterpoint Research figures.

CXMT went from under 1% in 2023 to 4% in Q2 2025, then 8% by the end of 2025. Analysts had not expected 10% until 2028. Capacity sits near 320,000 wafers a month, with a target of 420,000 by 2027. For a wider view of the field, see our list of memory RAM manufacturers for OEM buyers.

The G5 platform behind its newest LPDDR5X fits up to 50% more dies on each wafer, which is how CXMT keeps adding output without new fabs.
1. How Far Behind Is CXMT's Technology?
CXMT makes DDR5 on a 17nm class node, while Samsung, SK Hynix and Micron run their 1c nodes. That sounds like a wide gap, but DRAM doesn't shrink like CPUs do, because each cell needs a capacitor and capacitors are very hard to scale down. DDR5 yields are now reported above 90% in recent yield reports, and Micron needed 12 to 15 months for a similar climb in 2021. The real gap is cost, at roughly 30% more per bit than the big three.
2. Can CXMT Make HBM for AI?
Not at scale yet. Its HBM yields are modeled at around 25%, and most of the loss comes from stacking and packaging dies rather than the base DRAM. Analyst estimates place CXMT three to five years behind the Korean leaders in HBM.
Does CXMT Make Memory Cheaper?
Not directly. CXMT sells at market prices, the same level as the big three, because its higher cost per bit leaves little room to undercut them. The extra profit goes into new lines and R&D, which rose 87% in the first half of 2026.
That added output helps over time, since every new wafer eases total supply. Buyers hoping for a cheap alternative right now, though, won't find one. CXMT parts cost about what everyone else charges.

The DoD dates come from Section 805 defense contracting rules, and the federal date comes from the FY2023 NDAA. CXMT sued the Pentagon over its military company listing in August 2026. It isn't on the Commerce Department's Entity List, though a July 2026 Senate letter urged US firms to review their reliance on Chinese memory.

⚠ Selling to the US government?
If any of your products reach federal or defense buyers, check every memory part's die source now. The indirect ban covers components inside finished goods, so confirm the rules with compliance counsel before mid 2027.

How to Tell If Your Memory Uses CXMT Chips
Module brands rarely say whose DRAM dies sit on their sticks. Start by checking the markings printed on each DRAM package, since the chip maker's logo and part number appear there, not on the module label.
For volume orders, ask suppliers for a written die source declaration. Name the DRAM maker in your bill of materials and certificates of conformance, so a later audit takes minutes. This matters even for consumer goods, since laptops from HP, Asus and Acer sold outside the US reportedly already use CXMT memory.
How to Qualify CXMT as a Second Source
Supply is the first hurdle. CXMT gives Chinese customers such as Huawei, Xiaomi and Alibaba Cloud first call on output, and some global PC brands hold back to protect their supply deals with the big three. Foreign buyers should expect small allocations at first.
If you go ahead, plan a full qualification:
-
Confirm JEDEC compliance for the exact part, speed and density you need.
-
Test samples on your target platforms, including BIOS settings and memory training.
-
Run temperature and burn in testing that matches your product's real duty cycle.
-
Ship a pilot lot before full release, and budget 6 to 18 months for the whole process.

FAQs
What does CXMT stand for?
CXMT stands for ChangXin Memory Technologies. It is a DRAM maker based in Hefei, China, founded in 2016.
Is CXMT sanctioned by the United States?
Partly. It's on the Pentagon's Chinese military company list, which limits defense contracts, and federal agencies can't buy products with its chips from December 2027. It isn't on the Entity List.
Does CXMT make HBM chips for AI?
Only in small batches so far. HBM3E samples are in qualification with Chinese AI chip firms, and yields are modeled around 25%.
Is CXMT memory already in Western products?
Yes. Laptops from HP, Asus and Acer sold outside the US reportedly use CXMT memory, and Apple has reportedly explored it as a supplier.
Will CXMT lower DRAM prices?
Not soon. CXMT prices at market level, and its added output mainly eases overall supply over the next few years rather than cutting prices now.
Is CXMT DDR5 as good as Samsung or SK Hynix?
For mainstream speeds, it holds up well, with reported yields above 90%. It costs more to make per bit. Compare platform costs in our DDR4 vs DDR5 bulk buying guide.
Why does CXMT use an older process node?
US export rules limit its access to the most advanced chipmaking tools. It relies on multi step patterning to keep shrinking cells on the equipment it has.
Is CXMT a publicly traded company?
Yes. CXMT trades on Shanghai's STAR Market under the code 688825, after its July 27, 2026 listing.
