ChangXin Memory Achieves Key Breakthrough! LPDDR6 R&D Verification Nearly Complete, Aiming for Global First Mass Production in 2026

ChangXin Memory (688825-CN), a major Chinese memory manufacturer whose market capitalization surged to 3.6 trillion RMB within a week of its IPO, has recently made significant progress in next-generation low-power memory technology. It is reported that the company's LPDDR6 product has nearly completed its R&D verification phase, standing just one step away from formal mass production.

According to industry practice, LPDDR products must undergo several stages from development to market launch: die-level verification, R&D verification, small-batch validation, and finally mass production.

The current R&D verification stage involves comprehensive testing of compatibility, system stability, performance-power efficiency, and mechanical reliability, aiming to identify and eliminate potential risks early and confirm the reliability of product design.

This indicates that ChangXin has already passed the halfway mark in the commercialization process of LPDDR6.

In fact, as early as March this year, market rumors suggested ChangXin was actively sending LPDDR6 samples to key customers, potentially securing the title of world's first mass production in the second half of 2026.

However, news on this front went quiet for a while until resurfacing in August. Observers speculate this may have been due to the company's focus on accelerating its IPO timeline.

In terms of specifications, ChangXin's first LPDDR6 product features a design speed of 12,800 Mbps, with a base operating speed of 10,667 Mbps when working in tandem with system-on-chip (SoC). The single-die capacity is 16Gb, with a packaged chip capacity reaching 16GB, using a 1295-ball PoP (Package-on-Package) packaging technology.

Compared to the previous-generation LPDDR5X, the new product shows clear improvements in power efficiency, reliability, availability, and maintainability.

Looking back at ChangXin's technological evolution: at the end of 2023, it launched its first self-developed LPDDR5 series, with a die capacity of 12Gb and a speed of 6,400 Mbps; in 2025, it introduced the LPDDR5X series, expanding capacity to 12Gb and 16Gb, with speeds reaching up to 10,667 Mbps—66% faster than the previous generation—while simultaneously reducing power consumption by 30%.

In total, ChangXin has taken less than three years to transition from the launch of LPDDR5 to sending LPDDR6 samples to core customers, a pace of advancement that cannot be underestimated.

According to ChangXin's IPO prospectus, its LPDDR series products have already entered the supply chains of major smartphone brands such as Xiaomi (01810-HK), Transsion Holdings (688036-CN), Honor, OPPO, and vivo.

Supporting this technological push is sustained and increasing R&D investment. In 2025, R&D expenditure reached 9.593 billion RMB, a year-on-year increase of 51.28%. From 2023 to 2025, cumulative R&D investment exceeded 20.6 billion RMB, with a total of 6,972 patents accumulated.

However, ChangXin is not the only player in the race. In the LPDDR6 mass production race, South Korea's SK Hynix (KR000660) currently leads the pack. The company announced in March this year that it had completed the development and verification of the world's first LPDDR6 using the sixth-generation 10nm-class (1c) process with 16Gb capacity, also planning to start mass production and shipments in the second half of 2026.

In contrast, Samsung Electronics (KR005930) and Micron Technology (MU-US) have taken a more conservative approach. The two industry leaders have shifted more wafer production capacity toward higher-margin markets such as HBM and server memory, indirectly creating growth space for ChangXin.

Market research firm Omdia reports that ChangXin currently holds about 7.67% of the global market share. Broker Nomura Securities estimates ChangXin's current market share at around 10%, and forecasts it could rise to 18% by the end of 2028. In one research report, Nomura even referred to ChangXin as the "jewel in China's crown" and significantly raised its target price to 116 RMB.

Financially, ChangXin forecasts its revenue for the first half of 2026 to reach between 110 billion and 120 billion RMB, representing a year-on-year increase of 612.53% to 677.31%. Net profit attributable to the parent company is estimated at 50 billion to 57 billion RMB, an annual increase of over 25 times, demonstrating astonishing growth momentum.

Notably, beyond its existing Chinese smartphone brand customers, Apple (AAPL-US) has reportedly begun evaluating ChangXin for inclusion in its diversified memory supply chain.

The Financial Times reported on June 27 that Apple had contacted the U.S. Department of Commerce regarding the procurement of ChangXin's DRAM chips. On July 8, the newspaper further revealed that Apple had begun internal testing of ChangXin's DRAM chips, with initial plans to use them in product lines sold in the Chinese market.

At Apple's Q3 2026 fiscal earnings call on July 30, CEO Tim Cook personally addressed the issue of memory supply diversification, stating the company is "evaluating all options" and noting that the global DRAM market is currently dominated by just three suppliers. He added, "It would be beneficial for supply and potential pricing if more suppliers could join."

Analysts point out that while joining Apple's supply chain is significant, ChangXin's technological progress on LPDDR6 is even more indicative.

Successful mass production would signify that China's memory industry is steadily closing the technological gap with international first-tier manufacturers, potentially disrupting the long-standing rhythm of advanced memory technology updates dominated by Western, Japanese, and Korean firms, and introducing new variables into the global DRAM market landscape.
