With 17 years of technology accumulation and business expansion, the company has successfully built a full range of storage controllers and storage solutions from SATA to PCIe, from eMMC to UFS, from USB to SD, etc. Its subsidiary brand, SiliconGo, provides highly reliable storage solutions for enterprise, industrial, and automotive scenarios.
YEESTOR independently owns the core IPs of all storage controllers represented by LDPC and NVMe, as well as multiple core technologies covering various key links from the storage particle end, storage controller end to the host end of the storage controller. The company holds 290 domestic and foreign invention patents.
The company has successfully launched the first UFS storage controller in the Chinese mainland for the open market. In 2023, the company's SATA SSD controller accounted for nearly one-third of the global market share. From 2021 to 2023, the company ranked first in China in terms of market share of SSD storage controller for three consecutive years, and its shipments of SD/TF card storage controller led the global market. Meanwhile, the industrial memory products of the "SiliconGo" brand have been widely used in key infrastructure fields such as communications, energy, and electricity. The industrial-grade eMMC has been shipped in large quantities in the energy and power industry, with a leading market share in the industry.
YEESTOR is deeply involved in cutting-edge technological fields such as storage control, storage-computation integration, and storage-computation interconnection. It actively promotes the research, development, and layout of PCIe Gen5, CXL controllers, and storage-computation integrated chips, bringing customers more excellent and efficient storage solutions.
1. Technological innovation and product breakthrough: YEESTOR successfully launched the first UFS3.1 storage controller YS8803 for the open market in mainland China, becoming the first in China and the third independent UFS controller supplier in the world. Additionally, the company introduced the industry's first USB3.2 Gen1 single-channel solid-state USB flash drive controller that supports the UASP protocol and breaks through the "double 400" performance threshold. Furthermore, YEESTOR's latest fifth-generation LDPC technology provides excellent high-performance error correction algorithms, supporting error correction capabilities at the 4KB+ level, providing important technical support for memory chip innovation for global enterprise-level, data centers, and system manufacturers.
