According to the Chosun Ilbo, China's largest DRAM manufacturer Changxin Memory Technologies (CXMT) has launched trial production of the fourth-generation high bandwidth memory HBM3, with initial yield stagnating at 25%, about one-third of the golden mass production yield of 80%. SK Hynix has been mass producing similar products since 2022, with a yield exceeding 90%.The front-end yield of Changxin Memory's HBM3 8-layer stacked products is about 30%, while the back-end yield is approximately 70%, resulting in final good products. The company supplies a small number of samples to Chinese companies such as Alibaba's Pingtouge and Cambricon, and continues to improve yields. Its G4 (17-nanometer) process ordinary DRAM has no major issues, but the DRAM chips used for HBM have larger areas and stricter electrical specifications.The industry attributes the reasons to the insufficient maturity of Through-Silicon Via (TSV) technology. Nomad Semi's analysis shows that Samsung's HBM2 has over 5,000 TSVs per chip, SK Hynix's HBM3 has over 8,000, while Changxin Memory has about 3,000. There is a gap of 4 to 5 years compared to Samsung and SK Hynix.

According to the Financial Times, citing informed sources, Chinese memory chip manufacturers Changxin Storage and Yangtze Memory Technologies have purchased enough deep ultraviolet lithography machines (DUV) from ASML to meet their expansion plans for the next three years.

Changxin Technology held a performance briefing for the first half of 2026. An investor inquired about the third quarter DRAM price situation, and the company's Senior Vice President and Chief Financial Officer Huang Danyang believes that looking ahead to the second half of 2026, the global supply shortage of DRAM products will continue.

Changxin Technology held a performance briefing for the first half of 2026. The company's independent director Chen Wuchao stated in response to investor questions that in the first half of 2026, the global DRAM product market improved, and prices increased.Currently, the company is still in a critical investment period for capacity expansion and technological upgrades, and it needs to gradually create returns for shareholders while ensuring necessary capital expenditures. As profitability continues to strengthen, the company will legally and in accordance with regulations timely initiate the verification of the dividend plan.

According to Blue Whale News, from Changxin Technology, ByteDance and ZTE have jointly developed a new generation of Doubao phone------Nubia NaviX Ultra, which will be equipped with Changxin's highest speed LPDDR5X memory at 10667Mbps. The official statement indicates that this is also the first time that domestically produced 10667Mbps high-speed LPDDR5X memory chips have achieved mass production and application.Previous news reported that the Nubia "Doubao phone" has completed network filing and will be mass-produced and launched in September.

Changxin Storage filed a lawsuit against the U.S. Department of Defense on August 28, Eastern Time. Changxin Storage stated that the company filed a lawsuit in the U.S. District Court for the District of Columbia, accusing the U.S. Department of Defense of mistakenly listing it as a "Chinese military enterprise," with the company first being named in January 2025. Changxin Storage is not a military enterprise; it only researches and produces DRAM (Dynamic Random Access Memory) products for commercial and civilian use, and they are not used for military purposes.

The company has no controlling shareholder or actual controller, with the largest shareholder, Qinghui Jidian, holding 21.67%. The company was listed on the Sci-Tech Innovation Board on July 27, with an issue price of 8.66 yuan per share, and its market value exceeded 3.5 trillion yuan on the first day of trading.

According to on-chain analyst Yu Jin's monitoring, as Changxin Technology (CXMT) surged 5% to reach a market value of 4 trillion yuan, the largest short seller who shorted the day before Changxin's listing has incurred losses of up to 10.82 million dollars.This whale has held the position for a month, shorting 2.9 million shares of $CXMT at 6.5 dollars, which is now at 8.6 dollars. The price loss is 6.3 million dollars, and the funding fees already paid amount to 4.52 million dollars.

Changxin Technology announced that the overallotment option for its initial public offering and listing on the Sci-Tech Innovation Board has been fully exercised, corresponding to an additional issuance of 1.003 billion shares, increasing the total share capital to 67.884 billion shares.Since the stock price during the exercise period was higher than the issue price of 8.66 yuan per share, China International Capital Corporation, as the authorized joint lead underwriter for this issuance, did not use the funds obtained from the overallotment to buy back the issued shares from the secondary market through competitive trading.

According to DIGITIMES, Changxin Memory and Yangtze Memory continue to expand, and recently Apple is actively seeking to introduce the two Chinese memory supply chains, drawing attention to their entry into Apple's supply system. Industry insiders reveal that the two manufacturers are actually using Apple to prove that the quality of Chinese DRAM and NAND Flash has reached international standards, while secretly expanding their cloud and enterprise market share through third-party assembly for export to North American neocloud operators.Changxin Memory's parent company, Changxin Technology, has completed fundraising of 29.5 billion yuan, while Yangtze Memory plans to raise about 33 billion yuan through an IPO for production line upgrades and R&D. Yangtze Memory has turned profitable in 2024, with a net profit attributable to the parent company reaching 33.379 billion yuan in the first quarter of 2026; its third-phase new factory will begin production ahead of schedule in the fourth quarter of 2026, with a total monthly production capacity of 100,000 wafers, of which about 20% will be trial-produced LPDDR, becoming its first DRAM base. The supply chain indicates that the two companies are expected to increase the self-sufficiency rate of domestic memory in China to over 50% by the end of 2027 to 2028.Yangtze Memory sells NAND to third-party module manufacturers and assembles them into enterprise-level SSDs to avoid location sensitivity; Changxin Memory has already obtained certifications from small and medium-sized cloud operators in the U.S., Canada, and other regions. U.S. private enterprises can, in principle, procure from the two companies, with the entity list primarily restricting their access to U.S. technology, but not completely prohibiting private procurement. Cloud operators also reduce compliance risks through methods such as renting computing power or holding assets through third parties. The industry believes that Apple's influence on supply and demand in the industry is declining, and the two companies have no intention of supplying Apple in large quantities or engaging in price competition, making it difficult to meet Apple's demand in the Chinese market in the short term.

Xiaomi officially released the Xuanjie O3 chip. The new generation Xuanjie O3 is the world's first flagship mobile processor (SoC) that supports LPDDR6 memory chips. According to reporters from the Financial Associated Press, domestic storage leader Changxin Storage (CXMT) is a core partner for Xiaomi's Xuanjie O3 LPDDR6 memory.In March this year, there were reports that Changxin LPDDR6 had sent samples to key customers, and in early August, multiple media outlets reported that it was nearing the end of verification. With the launch of the Xuanjie O3, this marks the first application of domestic LPDDR6 chip products in flagship processors, which also means that domestic low-power memory has officially entered the global top tier.

According to a report by China Fund News, data from SEIBro, a subsidiary of the Korea Securities Depository (KSD), shows that as of August 18, the stock that Korean investors bought the most in A-shares over the past month is a mysterious stock.During this period, Korean investors net bought this stock for $45.322233 million (approximately 307.53 million RMB). Extending the timeframe to the past three months, this stock still ranks first in the net purchase list of A-shares by Korean investors. When trading this security, Korean securities firms, as qualified foreign institutional investors (QFI), must submit settlement instructions to KSD. The submission of settlement instructions requires the use of an ISIN code. Therefore, relevant Korean securities firms have chosen to temporarily use a temporary virtual code, and the name of the security is displayed based on the virtual ISIN.A search on SEIBro reveals that as of July 28, Changxin Technology had appeared among the stocks with the highest net purchase amounts by Korean investors in the previous week. However, as of July 27, Changxin Technology did not appear in the list of the top 50 A-shares by net purchase amount from Korean investors in the previous week (it is also possible that Korean investors had already bought it, but Changxin Technology did not make it into the top 50 A-shares by net purchase amount). This indicates that at the latest by July 28, which is the second day after Changxin Technology's listing, Korean investors had begun to buy.

According to the official announcement, Bitget's stock perpetual contracts have been launched for CXMT (Changxin Storage). The contract is settled in USDT, supports up to 20 times leverage, and allows trading 24/7. So far, Bitget supports a total of 273 stock perpetual contract underlying assets.

According to on-chain analyst Yu Jin's monitoring, a certain whale established a short position the day before Changxin Technology (CXMT) went public, and has held the position for about half a month without closing it. Currently, the scale of the short position is approximately 22.86 million USD, with an opening price of about 6.5 USD.During the holding period, this address has paid approximately 3.4 million USD in funding fees, while the unrealized loss on the short position is about 4 million USD, resulting in a total loss of approximately 7.4 million USD.Yu Jin stated that even if the price of Changxin falls back to its opening price of 6.5 USD, this address will still have to bear the high funding fee costs incurred during the holding period.

According to reports from Fast Technology, Changxin Memory's 17nm DDR5 chip yield has surpassed 90%, which is only about 2 percentage points lower than Samsung's same-generation products at 92% to 93%, marking a technical indicator that has entered the global first tier. Several major PC manufacturers have completed certification for Changxin DRAM chips around mid-year and have begun to incorporate them in small batches into certain laptops.The strategies adopted by different brands show significant differences: Dell has completely banned the use of Changxin chips; HP restricts their use to the mainland China market; Acer and ASUS have incorporated them into models aimed at the mainland China and emerging markets. Currently, the impact of Changxin products on the overall market prices of the three major memory giants remains limited, mainly because Samsung, SK Hynix, and Micron are currently more inclined to supply LPDDR5, while Changxin's current strategic focus is on expanding DDR5 shipments. Executives from PC companies have stated that the three major manufacturers hold over 90% of the global DRAM market share, and large-scale adoption must be approached with high caution. Currently, the number and usage of models using Changxin chips are quite limited.

According to Ai Yi's disclosure, the on-chain Changxin Storage TOP1 Air Force holds approximately $21.12 million in 1x leveraged CXMT short positions, with an entry price of around $6.5. The current price has risen to $7.28, resulting in an unrealized loss of about $2.255 million. Meanwhile, the total funding fees paid by this short position have reached $3.078 million.This position previously invested over $40 million in margin, and there is still a significant gap to the liquidation price of $15.466. However, the continuously accumulating funding costs are eroding profits, and the market speculates that this trader may still be betting on a significant correction in CXMT's price to cover current losses and achieve profitability.

According to The Wall Street Journal, Apple is testing memory chips from the Chinese DRAM manufacturer Changxin Storage (CXMT), planning to apply them to product lines such as the iPhone and MacBook. The background of this move is the AI demand driving up global memory prices; Apple has previously lobbied the U.S. side, stating that the current pricing from Korean and American suppliers is "unsustainable." The report states that Apple is seeking approval from the White House to conduct business with Chinese chip suppliers. Currently, the U.S. allows the purchase of commercial off-the-shelf chips but restricts customized products.Changxin Storage has recently rapidly expanded its market share, with second-quarter revenue growing more than 8 times year-on-year, and its global DRAM market share rising to 7%, completing its IPO on the Science and Technology Innovation Board last month. Meanwhile, PC manufacturers such as HP and Acer have begun using Changxin Storage memory chips in some devices sold in non-U.S. markets to alleviate supply pressure. If Apple ultimately reaches a procurement agreement, it may face political resistance from Washington.

According to South Korea's Digital Daily, Apple has recently negotiated with Changxin Memory Technologies (CXMT) on the supply prices of mobile DRAM such as LPDDR5X to reduce costs for the next generation of iPhones and smart devices, but was rejected. Changxin Memory insists on maintaining a price level comparable to or even higher than that of Samsung Electronics and SK Hynix, breaking Apple's usual bargaining advantage as an end manufacturer.The report analyzes that Chinese terminal companies such as Huawei and Xiaomi have locked in a large amount of Changxin Memory's production capacity through long-term high-price contracts, providing a solid price defense line in the domestic market. Meanwhile, Samsung Electronics and SK Hynix are facing reduced supply of general DRAM due to the continuous expansion of HBM capacity, combined with Changxin Memory holding the price floor, significantly alleviating the shipping pressure and price decline risks for Korean manufacturers in the general DRAM sector, allowing them to focus resources on high-value AI storage products such as HBM4, LPCAMM2, and eSSD. Industry insiders expect that in the second half of the year, the operating profit margins of the Korean semiconductor camp and global market pricing power will further strengthen.
