So far, IC design companies in China, Japan and South Korea have not tried to challenge the dominance of American companies in the field of high-end memory controller chips. Its energy is mainly concentrated on the PC side, starting a competition mode based on the detailed specifications of consumer-grade and industrial-grade products, and its market awareness and status of large-capacity storage systems is vague. The industry believes that the domestic storage market, especially domestic SSDs, will explode in 2020 and attack major international manufacturers head-on.
Solid state drive (SSD) mainly includes three major components: main control chip, flash memory particles and cache unit. Among these three major items, the most expensive one is flash memory particles, which account for about 70% of the market share. Currently, only Yangtze Memory can provide them in China; due to different manufacturers’ positioning issues for different products and the distinction between internal and external caches in some products, the cache Units generally cannot be discussed uniformly; but the main control chip has the most technical content and core technology. Domestic manufacturers that can provide SSD main control mainly include Deyi Microelectronics, Lianyun Technology, Yixin Technology, Hualan Microelectronics, etc. company.
Shenzhen Deyi Microelectronics Co., Ltd. (hereinafter referred to as "Deyi Microelectronics") was formed by the merger of two companies, SiG Semiconductor (founded in 2007) and Lierding Technology (founded in 2015). Deyi Microelectronics focuses on Focused on consumer-level and enterprise-level solid-state storage control chip design and services, it has a mature storage control chip design process. In 2019, it has completed the layout from consumer-level to enterprise-level, and its products cover entry-level consumer level, high-end consumer level and even enterprise-level solid state drives. A full range of controllers, the products are mainly SSD, eMMC, USB, SD and other main control chips and Security Storgage Controller, which are widely used in the fields of mobile storage, portable storage and secure storage.
Deyi Microelectronics established a project to develop SSD controllers in 2015. It was launched and mass-produced in 2019, with millions of units shipped in the same year. Luo Ting, marketing director of Deyi Microelectronics, once told electronics enthusiasts, “With more than ten years of accumulation of technology and experience in the field of solid-state storage, and after 3 to 4 years of continuous polishing, the company’s SSD storage control chip products have become popular once they are launched. Quickly gaining market recognition.
In 2019, Deyi Microelectronics fully entered the solid-state storage main control market, from consumer level to enterprise level, from SATA to PCIe, and its products include YS9081XT/YS9083XT SATA 3.2 SSD main control chip, YS9201/YS9203 PCIe SSD Products such as main control chips received a large number of cooperation inquiries soon after their launch, and have reached cooperation with a number of solid-state drive manufacturers such as Zhiyu Technology and Taipower Technology.
It is undeniable that 2019 is the year for Deyi Microelectronics. The SSD solid-state drive market has had a very fruitful year. It and Netac have joined forces to adopt Deyi Microelectronics' SATA YS9083XT flash memory master chip for Netac's 2.5-inch SSD products. This master chip uses enhanced 2K The code-length LDPC intelligent error correction algorithm significantly improves reliability and durability, and is remarkable in main control performance. The new generation solid-state drive jointly created by Netac and Deyi Microelectronics uses the main control device of Deyi Microelectronics. While controlling the chip, it has independent research and development, design, firmware development, and manufacturing in the entire process. It is an absolutely domestically produced and controllable SSD product, taking a milestone step towards "domestic core".
PCIe SSD main control chip product details
In terms of products, the PCle SSD main control chip released by Deyiwei fully utilizes the performance of NVMe1.3. It currently has two models, YS9203 and YS9201, with excellent performance. It supports 3D MLC/TLC/QLC NAND and uses LDPC, Enhance RAID, End -to-End, providing comprehensive data protection and enhanced durability and retention of 3D NAND, suitable for consumer and light enterprise applications. On June 28, Deyi Microelectronics relied on the PCIe3x4 SSD master YS9203 storage control chip.
SATA SSD main control chip product details The
SATA SSD main control chip series currently has two models, US9082HC and YS9083XT, which can help customers achieve cost-effective consumer-grade products. and industrial-grade SSD solutions, including 2.5-inch SSD, 1.8-inch SSD, Slim SATA, mSATA, M.2 and Micro SSD form factor SSDs, suitable for desktop computers, notebook computers and other embedded applications.
In response to domestic independent and controllable needs, Deyi Microelectronics launched the Tianxing Plan based on its independent intellectual property layout, providing PCIe, SATA, eMMC, UFS, SPI NAND, USB, etc. for servers, computers, mobile phones, mobile storage and other application fields. A package of fully autonomous and controllable storage solutions including SD. With 13 years of technology accumulation and business expansion, Deyi Microelectronics has established a complete storage product line from general storage (USB/SD), embedded storage (UFS/eMMC/SPI-NAND) to SSD (SATA/PCIe) storage, accumulating Shipped more than 1 billion units.

Tianyancha information shows that Deyiwei was established in November 2017 with a registered capital of approximately 45.617 million yuan. Shenzhen Zhicun Microelectronics Enterprise (Limited Partnership) currently holds 16.92% of Deyiwei. Major shareholder, it owns 100% holdings of Hefei Zhicun Microelectronics Co., Ltd. and Shenzhen Silicon Semiconductor Co., Ltd. The successful acquisition of Shenzhen Daxin Electronic Technology Co., Ltd. (EpoStar) in April 2020 also announced that Yiwei has completed the full product line layout of storage control chips from mobile storage, embedded storage to SSD, providing consumer and enterprise customers with One-stop storage control solution. Wu Dawei is the legal representative, chairman and general manager.
Deyiwei is headquartered in Shenzhen and has branches in Hsinchu, Hong Kong and Hefei, Taiwan. It currently has more than 200 employees, of which R&D personnel account for as much as 80%. On April 15, 2020, DeYiWei completed Series B financing, led by Alphatecture, a US dollar ecological fund affiliated to a world-renowned chip IP company, with participation from Delian Capital, Walden International and others. The transaction amount has not yet been disclosed.
With the increasingly strong market demand and China's strong support for semiconductors in recent years, domestic SSD master control brands have gradually emerged. At present, there are thirty or forty domestic manufacturers claiming to be making SSD controllers, including Lianyun Technology, Yixin Technology, Guoke Micro, etc.
Lianyun Technology is the third company in the world after MARVELL in the United States and SMI in Taiwan and the only domestic manufacturer capable of large-scale mass production of SSD main control chips. Its MAS0901 solid-state drive main control chip is an enterprise-level solid-state drive solution whose performance has reached the international level. Leading the way in solid-state drive main control chips and solid-state drive solutions, it completed the A+ round of financing in December 2019; Yixin Technology is the earliest start-up in China dedicated to the research and development of high-performance SSD main control chips and completed the project in August 2018. B round of financing, and received equity financing from Paradise Silicon Valley on May 18, 2020; Guokewei is a key integrated circuit design company within the national planning layout, and is also the first integrated circuit design to receive investment from the National Integrated Circuit Industry Investment Fund Enterprise, its second generation GK2301 has completely independent intellectual property rights and has passed the dual certification of the State Cryptozoology Administration and the China Information Security Evaluation Center.
