Progress in AISmart Chips

AIchips are a highlight in the breakthrough of domestic chips.

  • Performance Improvement: Huawei Ascend910Bchip has surpassed NVIDIAH100by67 TFLOPSinFP16computing power (256 TFLOPS).
  • Ecosystem Building: The success of domesticAIchips lies not only in hardware but also in software and ecosystem.Moore Threads’sMUSAarchitecture,Chipone’sNPUaccelerators are supporting the domesticAIecosystem.DeepSeek-V3.1 large model adoptsFP8precision solutions, effectively optimizing the computing power resource allocation of domestic chips.
  • Market Replacement: After the US banned the sale ofH20chips, Huawei Ascend910Bhas achieved a replacement rate of over60%in the domestic market.

Breakthroughs in Storage Chips

Storage chips are the cornerstone of the information industry.

  • Flash Memory (NAND): Yangtze Memory Technologies has achieved the world’s first mass production of232layers3D NANDflash memorytechnology, breaking the foreign monopoly.
  • Memory (DRAM): Changxin Memory has made progress inLPDDR5Xmemory chips, with its self-developed“Rock Solid”architecture reducing power consumption by40%, and has adapted to HarmonyOSPC.
  • Key Technology Breakthrough: Lingkai Semiconductor announced the breakthrough and mass production ofembedded flash memory (e-Flash) below28nmin August 2025. This technology is widely used in IoT terminals, automotive electronics,AIedge computing, etc. Its read and write speed is improved by40% compared to40nm, and power consumption is reduced by25%, and it has passedAEC-Q100 automotive certification, which is significant for domesticMCUs, automotive electronics, and other fields.

The “Battle for Semiconductor Equipment and Materials”

Semiconductor equipment and materials are the cornerstone of chip manufacturing and the focus of domestic industry efforts.

  • Etching Equipment: SMEE’s5nmetching machine has reachedinternational leading level and is used in international advanced production lines.
  • Lithography Equipment: Shanghai Microelectronics’s90nmlithography machine has been commercialized, but there is still a significant gap compared to the most advanced internationalEUVlithography machines.
  • EDATools: Domestic companies such as Huada Jiutian have supportedEDAtools (chip design software) for processes above28nm, but more advanced EDA tools are still mainly dominated by American companies.
  • Materials: The localization rate of materials such as high-purity silicon wafers and photoresists is still less than30%.
