On July 28, 2026, CrossChip, a global leading flash memory solution provider, announced that its latest UFS 4.0 (Universal Flash Storage 4.0) flash chip has passed full certification from multiple mainstream phone manufacturers including Samsung, Xiaomi, and OPPO, and is expected to be mass-produced in flagship smartphones in the second half of 2026. The chip achieves a sequential read speed of 4.6GB/s and a sequential write speed of 4.2GB/s, representing an approximately 80% improvement over the previous UFS 3.1 generation, while reducing power consumption by 30%. This milestone marks the official entry of mobile storage into the 4GB/s era.
Technical Breakthrough: Comprehensive Innovation from Interface to Stacking
CrossChip's new-generation UFS 4.0 flash memory is based on its seventh-generation 3D NAND flash architecture, combined with a new controller and interface design. According to CrossChip's official disclosure, the product adopts 176-layer stacking technology with a storage density of 1Tb per die, enabling up to 1TB capacity in a compact package. Meanwhile, the UFS 4.0 interface supports MIPI M-PHY 5.0 and UniPro 2.0 protocols, with theoretical bandwidth increased to 23.2Gbps per channel, double that of UFS 3.1. In addition, CrossChip has introduced adaptive voltage regulation and intelligent write acceleration technologies, improving random read/write performance by over 50% compared to the previous generation, particularly suitable for large application loading, 4K/8K video recording, and AI on-device inference scenarios.
Automotive-Grade BGA SSD: Extending to Automotive Electronics
In addition to mobile flash memory, CrossChip simultaneously announced the launch of a BGA SSD solution for the automotive market, model CrossChip AutoDrive BGA SSD. The product uses a UFS 4.0 interface package, but with additional ECC error correction and AEC-Q100 Grade 2 certification, the operating temperature range is extended to -40°C to 105°C. Sequential read speed reaches 4.2GB/s and sequential write speed 3.8GB/s, meeting the real-time data storage requirements of advanced driver assistance systems (ADAS), in-vehicle infotainment systems, and domain controllers. CrossChip stated that it has signed cooperation orders with three Tier 1 suppliers and expects mass production in 2027.
Industry Insight: UFS 4.0 Accelerates Mobile AI Application Deployment
With the explosion of on-device large language models (LLMs) and generative AI, the demand for storage bandwidth and capacity in smartphones has significantly increased. Industry analysts point out that the widespread adoption of UFS 4.0 will enable phones to load large model parameters faster and support smoother local AI inference. For example, flagship phones equipped with UFS 4.0 can reduce the loading time of GPT-3-level models from seconds to milliseconds. CrossChip passing certification from mainstream manufacturers means its technology maturity has met mass production requirements. Financial research institution IDC estimates that global UFS 4.0 flash memory shipments will exceed 300 million units in 2026, accounting for 35% of the mobile flash memory market, and CrossChip, with its first-mover advantage, is expected to capture 40% of that share.
Competitive Landscape: CrossChip vs Samsung, SK Hynix
In the UFS 4.0 field, Samsung launched its product first in 2023, followed by SK Hynix. CrossChip, as a latecomer, has surpassed them in performance parameters. According to Tom's Hardware benchmarks, CrossChip's UFS 4.0 chip leads Samsung's equivalent by about 15% in random read IOPS (Input/Output Operations Per Second) and has 10% lower power consumption. In addition, CrossCchip uses a unique wafer-level packaging technology that reduces chip thickness by 20%, which is more conducive to phone internal space design. This advantage has attracted multiple Chinese phone manufacturers to prioritize procurement.
Future Outlook: Moving Toward UFS 5.0 and Higher Capacity
While releasing UFS 4.0, CrossChip also revealed its roadmap for the next-generation UFS 5.0. According to the plan, UFS 5.0 will be based on its eighth-generation 3D NAND (expected 300+ layers), with interface bandwidth doubled to 46Gbps per channel, and sequential read speed expected to exceed 8GB/s. At the same time, CrossChip is actively deploying QLC (Quad-Level Cell) technology in UFS to reduce costs and launch 2TB or even 4TB mobile flash memory products. For investors, CrossChip's continuous iteration in flash memory technology will consolidate its leadership in the global semiconductor storage market.
Market Reaction and Investment Advice
As of the close on July 28, 2026, CrossChip's stock price rose 4.2% to $128.5, hitting a three-month high. Multiple investment banks have upgraded their ratings with a target price of $150. Analysts believe that the certification breakthrough of UFS 4.0 and the launch of automotive-grade new products are the main near-term catalysts. Investors should pay attention to flagship phone shipments in the second half of the year and CrossChip's market share changes in the automotive market. Overall, the flash memory industry is undergoing a structural shift from PC/servers to mobile and automotive fields. CrossCchip is expected to benefit continuously from its technology and capacity advantages.
Summary
CrossChip's UFS 4.0 flash memory passing certification by mainstream phone manufacturers not only validates the technical strength of its seventh-generation 3D NAND but also opens up two incremental markets: mobile and automotive. With the explosion of demand for on-device AI and smart cars, high-performance flash memory will become an indispensable component. For investors concerned about the semiconductor industry chain, CrossChip's flash memory update is worth continuous tracking.
