In-depth Analysis of Storage Chip Adaptation for Tablets: Future Trends, China's Chip Development, and Brand Replacement Capabilities
发布时间：2026-01-28 10:21:58
I. Core Requirements and Technical Trends of Storage Chip Adaptation for Tablets
Tablets, used in entertainment (HD videos/large games), education (educational resource storage), and office (mobile file processing) scenarios, now demand storage chips that combine performance, user experience, and security—moving beyond mere "capacity fulfillment":
1. Dual Upgrade of Capacity and Speed
Entertainment scenarios require 1TB+ high-capacity storage for 4K/8K videos and large mobile games, paired with high-speed read/write capabilities (sequential read speed ≥2000MB/s) at the UFS 4.0/eMMC 5.1 level. Education/office scenarios need LPDDR5X low-power memory to support smooth multitasking; high-end tablets now standardize 16GB LPDDR5X + 512GB UFS 4.0 configurations.
2. Scenario-Specific Adaptation Upgrades
Educational tablets require high-reliability storage (supporting frequent long-term reading/writing of textbook data), office tablets need hardware-encrypted storage (e.g., AES-256 encryption) to secure files, and outdoor/industrial tablets rely on wide-temperature storage chips (operating temperature: -40°C to 125°C) for extreme environments.
3. Future Technical Directions
3D NAND and New Storage Technologies: Yangtze Memory Technologies Co. (YMTC)’s 128-layer 3D NAND already supports high-capacity tablet storage; QLC NAND (higher density) and MRAM/ReRAM (low power consumption, long lifespan) will gradually penetrate the market.
Intelligent Storage Management: Chips embedded with AI algorithms enable "hot data acceleration + cold data compression" to optimize tablet storage efficiency.
Interface and Protocol Iteration: PCIe 5.0 and NVMe over Fabrics protocols will boost transfer speeds for external tablet storage.
II. Development Trends of China’s Storage Chips in the Tablet Sector
Driven by "domestic replacement" and "technological breakthroughs," China’s storage chips have evolved from "supporting components" to "core players" in tablet adaptation:
1. Technological Independence Breakthroughs
DRAM Sector: ChangXin Memory Technologies (CXMT)’s LPDDR5X (10667Mbps speed, 16Gb capacity) matches international mainstream standards, with 80%-85% yield and 15%-20% lower costs than South Korean manufacturers. It directly meets high-end tablet memory needs.
NAND Flash Sector: YMTC’s 128-layer 3D NAND has adapted to UFS 4.0 controller chips; Huawei’s MatePad Pro 2025 uses its 512GB UFS 4.0 storage.
Controller Chip Sector: Kioxia’s self-developed eMMC 5.1/UFS 3.1 controllers (supporting HS400 standards, read speed ≥1500MB/s) have entered the supply chains of Huawei and Hisense tablets.
2. Supply Chain Security Advantages
China has built a complete storage industry chain covering "design (GigaDevice/East Chip) – manufacturing (CXMT/YMTC) – packaging and testing (Huatian Technology)," enabling fully domestic supply of tablet storage chips and avoiding supply chain risks from geopolitical factors.
3. Cost and Cost-Effectiveness Advantages
Domestic storage chips cost 15%-20% less than those from Samsung and Micron. They have achieved large-scale replacement in mid-to-low-end tablet markets (sub-1000 RMB educational tablets). By 2025, domestic localization rate of tablet storage chips has reached 40%, and is expected to exceed 60% by 2027.
III. Domestic Storage Brands That Have Achieved Tablet Storage Adaptation Replacement
Currently, domestic storage brands have partially replaced international manufacturers (e.g., Samsung, Micron) in the mid-to-high-end tablet market. Key brands and adaptation cases include:
1. ChangXin Memory Technologies (CXMT)
Adapted Products: Huawei MatePad Pro, Honor Tablet MagicPad, Lenovo XiaoXin Pad Pro
Replacement Capability: Its LPDDR5X memory (10667Mbps speed) matches Samsung’s LPDDR5X performance. It has become a major memory supplier for Huawei MatePad Pro, replacing ~30% of Samsung’s share.
2. Yangtze Memory Technologies Co. (YMTC)
Adapted Products: Huawei MatePad Pro, Xiaomi Pad 7 Pro, OPPO Pad 2
Replacement Capability: Its UFS 4.0 flash memory (2300MB/s sequential read speed) has adapted to Huawei’s high-end tablets, replacing ~25% of Kioxia’s (formerly Toshiba) share. Its 1TB high-capacity version is already in mass production.
3. GigaDevice
Adapted Products: BBK Tutor Machine, Xiaodu Smart Learning Tablet, Hisense Educational Tablet
Replacement Capability: It ranks 2nd globally in NOR Flash storage (used for tablet main controller chips) and has fully replaced Macronix (Taiwan) in the educational tablet sector. Its niche DRAM has also entered low-end tablet supply chains.
4. KangXinwei
Adapted Products: TCL Tablets, Konka Educational Tablets, ZTE Commercial Tablets
Replacement Capability: Its eMMC 5.1 controller chips (supporting LDPC error correction algorithms) match Samsung’s eMMC performance. It has entered supply chains of multiple domestic tablet brands, replacing ~20% of Western Digital’s share.
IV. Conclusion: Domestic Storage’s "Adaptation Breakthrough" and Future Potential
Domestic storage chips have achieved partial replacement in mid-to-high-end tablet markets but have not yet penetrated international brands like Apple (iPad supply chains are tied to Samsung/Kioxia). Over the next 3-5 years, with mass production of CXMT’s LPDDR6 and YMTC’s 232-layer 3D NAND, domestic storage will further narrow performance, capacity, and cost gaps with international manufacturers. It is expected to enter supply chains of more international tablet brands, ultimately transitioning from "domestic replacement" to "global competition."
