[News] Bypassing U.S. Restrictions? CXMT Showcases GAA Technology for 3nm Chips

According to a news report from UDN, despite U.S. restrictions on the exportation of technologies related to advanced semiconductor processes, China is fortifying its independent chip development capabilities.

ChangXin Memory Technologies (CXMT), a Chinese DRAM chip manufacturer, presented a paper at the 69th IEEE International Electron Devices Meeting (IEDM) in San Francisco, showcasing a Gate-All-Around (GAA) technology applicable to cutting-edge 3nm chips.

According to an article from South China Morning Post, while CXMT has not yet released sample products, the evidence of the company’s next-generation memory production has caught the attention of industry analysts. This is noteworthy because the design of such chips typically involves technology subject to U.S. export restrictions.

Frederick Chen, a memory expert at Winbond Electronics, a Taiwan-based company, said the evidence of progress by CXMT is “impressive”, as it shows that the Chinese company is not far away from state-of-the-art research and products. “It’s significant because Samsung Electronics is trying to do the same.” Chen said.

Regarding this matter, CXMT has maintained a relatively low profile. Reportedly, in a statement to the South China Morning Post on Wednesday, CXMT stated that the paper “describes fundamental research related to DRAM structure and the feasibility of 4F2 design” and “it has nothing to do with CXMT’s current production processes.” This may have implied that the conceptual design is still distant from becoming a market-ready product.

“Any accusation that CXMT is violating US sanctions or export controls is completely inaccurate,” the company’s export control experts said. “We firmly believe that the free flow of ideas that IEDM seeks to foster is essential for the industry’s innovation and development.”

At the end of this November, CXMT released China’s first LPDDR5 chip, marking the entry of Chinese manufacturers into the DDR5 competition and narrowing the technological gap with leading memory suppliers such as South Korea’s Samsung and SK Hynix.

[News] CXMT’s LPDDR5 Release Fuels in Chinese Memory Market, Spotlight Progress of Global Memory Giants

On November 28, CXMT made a highlight in the Chinese market by unveiling its latest DRAM LPDDR5. It becomes the first company in China to self-develop and manufacture such DRAMs. CXMT said it has already received validation from major Chinese smartphone brands like Xiaomi and Transsion, signaling plans for swift market commercialization.

This launch not only improves the quality and cost-effectiveness of applications in personal and business sectors but also accelerates the industrialization of the Chinese DRAM industry, positioning CXMT at the forefront of the LPDDR5 era.

Latest Developments in CXMT’s LPDDR5 Strategy

The “LP” in LPDDR stands for Low Power, representing a type of Synchronous Dynamic Random Access Memory (SDRAM) product with lower power consumption compared to DDR. The JEDEC(Solid State Technology Association) categorizes DRAM into three kinds based on different application needs: Standard DDR, LPDDR, and GDDR. DDR is primarily used in servers and PCs, LPDDR in mobile phones and consumer electronics, and GDDR in image processing.

LPDDR5, the fifth generation of low-power double data rate synchronous dynamic random access memory, is the latest focus for CXMT. The company officially launched its LPDDR5 series, including 12Gb LPDDR5 chips, 12GB LPDDR5 chips with package on package (PoP) packaging, and 6GB LPDDR5 chips with die stacking chip (DSC) packaging.

CXMT’s LPDDR5 chips incorporate robust RAS (Reliability, Availability, and Serviceability) features, utilizing on-die error correction code (ECC) technology for real-time error correction, minimizing system failures, ensuring data security, and enhancing stability.

International Memory Giants Vying for Market Share

In September 2023, Samsung announced the development of a series of Low-Power Compressed Additional Memory Modules (LPCAMM), utilizing LPDDR5X memory. During the “2023 Investor Forum” held in Hong Kong in November, Samsung revealed plans to prepare new memory solutions for the automotive sector, including the new LPDDR5X.

SK Hynix officially supplied customers with 16GB capacity LPDDR5T (Low Power Double Data Rate 5 Turbo) products in November, marking the fastest mobile DRAM product with a transmission speed of up to 9.6Gbps.

Micron introduced LPDDR5X DRAM in 2022, with its LPDDR5X-9600 utilizing the latest 1β process technology. With a maximum capacity of 16GB, its speed is 12% higher than the previously fastest LPDDR5X-8533.

Promising Future for LPDDR5 Market

From the current DRAM market share perspective, TrendForce’s statistics on industry revenue from the second quarter show that Samsung has a market share of 39.6%, SK Hynix has 30.1%, and Micron (25.8%), together accounting for over 95% of the market share. Including Nanya Technology (2%) and Winbond Electronics (0.9%), the top five companies account for 98.4%.

Although industry points out that, compared to global giants, China-produced LPDDR5 currently has certain gaps in terms of capacity, speed, and other aspects, it is essential to note that LPDDR5 is trending towards becoming the mainstream in smartphone products. CXMT’s entry into this field coincides with the boom in LPDDR5 development.

TrendForce’s recent research on LPDDR indicates that LPDDR4X remains predominant in the mainstream market, with LPDDR5(X) focus on the high-end market for smartphones. However, with the introduction of Intel’s new Alder lake platform, LPDDR5(X) is gaining prominence in the laptop sector. It is estimated that the market share of LPDDR5(X) will exceed 25% in 2023.
