Yeestor

YEESTOR Microelectronics Co., Ltd. is a key Chinese firm specializing in the design and sale of storage controller chips. The company was established in 2017 through the merger of SiliconGo Microelectronics (founded in 2007) and Auspitek. This strategic consolidation was followed by the acquisition of EpoStar Electronics in April 2020, a move that secured essential patents and broadened YEESTOR's technological portfolio in memory controller chips.

The company's business model is centered on the research, development, and sales of storage control chips and comprehensive storage solutions. YEESTOR's revenue is generated through the sale of its three main product lines: solid-state drive (SSD) controllers, embedded storage controllers, and expandable storage controllers. It also provides storage control IP, complete memory products, and technical services, positioning itself as a one-stop-shop for its clients. These clients include manufacturers of data centers, servers, personal computers, smartphones, and automotive electronics. The firm serves as a critical supplier to well-known consumer electronics brands like Teclast.

YEESTOR offers a wide array of products, including PCIe SSD, SATA SSD, UFS, eMMC, USB, and SD controllers. These components are integral to the functioning of modern digital devices, managing the flow of data to and from flash memory. A notable product is the YS9203, a high-performance PCIe Gen3x4 SSD master controller suitable for both consumer and enterprise applications. The company has also developed controllers specifically for the growing automotive and industrial sectors, with a focus on creating products that meet stringent standards like ISO 26262. In 2022, YEESTOR applied for an IPO on Shanghai's Sci-Tech Innovation Board to fund the development of its next-generation enterprise, data center, industrial, and automotive controllers, although this was later cancelled.
