ChangXin Memory Particles

III. Technical Highlights and Domestic Significance

1. Autonomous Control: LongXin is the only domestic manufacturer capable of mass-producing mobile DRAM, breaking the monopoly of the three global giants: Samsung, SK Hynix, and Micron.

2. Performance on Par with International Leaders: The 6400Mbps speed reaches the level of contemporary mainstream international LPDDR5, with power consumption comparable to that of Samsung's same-specification products.

3. Full-Stack Self-Research and Development: Complete mastery of the entire process from DRAM particle design, manufacturing process to packaging and testing.

4. Ecosystem Compatibility: Pin definition is fully compatible with JEDEC standards, allowing direct replacement of overseas manufacturer particles with low switching costs for mobile phone and tablet manufacturers.

IV. Application Scenarios

1. Smartphones: Mid-range and flagship domestic smartphones, especially models emphasizing 'full domestication'.

2. Tablets and Portable Devices: Android tablets, 2-in-1 computers.

3. AIoT and Edge Terminals: Smart cockpits, AR glasses, industrial handheld terminals.

4. Automotive Electronics: Automotive-grade versions for smart cockpit domain controllers (meeting AEC-Q100 standards).

V. Industrial Background

• LongXin Memory is headquartered in Hefei, established in 2016, began mass production of DDR4 in 2020, and launched LPDDR5 around 2023.

• The global DRAM market was previously monopolized by Samsung (≈40%), SK Hynix (≈30%), and Micron (≈20%). LongXin is the fourth global manufacturer capable of mass-producing LPDDR5.

• Accompanied by domestic CPU/SoC platforms, it is a key link in 'de-Americanization' of the domestic consumer electronics supply chain.
