2. What is a Storage Chip?
In the digital world, if the CPU (Central Processing Unit) is the “brain” that performs thinking and calculations, then the storage chip is responsible for storing and retrieving information, acting as a “digital memory sponge” or “data granary”.
In simple terms, the photos taken on our phones, the videos downloaded, the apps installed, the documents and games on our computers, as well as the vast data centers that support the entire internet, are all stored in various types of storage chips. Without them, all data would have nowhere to be stored, and digital life would be unimaginable. Functionally, it is like the memory area in our brain, responsible for “remembering” important information and quickly “recalling” it when needed. Therefore, storage chips are the cornerstone of the information age, and their importance is self-evident.
3. Overview of Core Companies in the Storage Chip Industry Chain
The storage chip industry chain is very long, with interlinked segments and high technical barriers. We can simplify it into three core segments: upstream, midstream, and downstream.
(1) Upstream: The “Materials” and “Equipment” that Lay the Foundation of the Industry
The upstream is the foundation of the entire industry chain, primarily providing high-purity raw materials and high-precision equipment for chip manufacturing. Without self-controlled upstream resources, the midstream and downstream industries would be constrained.
-
North Huachuang
A leading domestic semiconductor equipment platform, with a product line covering multiple key processes such as etching and thin film deposition.
-
SMIC
A global leader in plasma etching equipment technology, a key tool supplier for microstructure engraving in chips.
-
Shanghai Silicon Industry
A leading domestic supplier of large-size silicon wafers, providing the most basic and core raw material wafers for chip manufacturing.
-
Shengmei Shanghai
A global leader in semiconductor cleaning equipment, with unique advantages in single wafer cleaning technology.
-
Yake Technology
A leading domestic supplier of semiconductor precursor materials, providing key “inks” for chip thin film deposition.
(2) Midstream: The “Heart” of the Industry Chain – Chip Design and Manufacturing
The midstream is the segment with the highest concentration of technology and capital, responsible for transforming upstream materials and equipment into actual chip products, including chip design, wafer manufacturing, and processing.
-
SMIC
The largest and most advanced wafer foundry in mainland China, serving as the capacity cornerstone for chip manufacturing.
-
Huahong Semiconductor
A global leader in specialty process wafer foundries, with strong capabilities in embedded non-volatile storage.
-
GigaDevice
A domestic leader in NOR Flash storage chip design, actively expanding into self-developed DRAM, setting benchmarks in the design field.
-
Unisoc
A leader in special integrated circuits and smart security chips, holding an important position in the special memory field.
-
Beijing Junzheng
A leading embedded CPU chip design company, entering the automotive-grade storage and analog chip market through acquisitions.
(3) Downstream: The “Bridge” Connecting Applications – Packaging, Testing, and Modules
The downstream is responsible for cutting, packaging, and testing the completed wafers, ultimately assembling them into storage products (such as SSDs, memory sticks, etc.) that consumers can directly use.
-
Changdian Technology
A global leader in semiconductor packaging and testing, providing advanced packaging solutions for domestic and international chip giants.
-
Tongfu Microelectronics
One of the leading players in the domestic packaging and testing industry, deeply integrated with global CPU/GPU giants, with strong technical capabilities.
-
Hua Tian Technology
A leading domestic integrated circuit packaging and testing company, with comprehensive layouts in multiple sub-packaging fields.
-
Jiangbolong
A leading domestic storage module company, owning the internationally renowned brand Lexar, with strong channel capabilities.
-
Bawei Storage
One of the few domestic memory manufacturers with integrated “research, production, and testing” capabilities, providing one-stop solutions.
