LSI Corporation

LSI Corporation was a prominent American technology company specializing in the design and manufacture of semiconductors and storage systems. Founded during the early integrated circuit boom, it became a key supplier of components for the data storage and computer networking industries. The company was publicly traded on the New York Stock Exchange before its acquisition by another major player in the semiconductor industry.

History

The company was founded in 1981 by industry veteran Wilfred Corrigan, who had previously led Fairchild Semiconductor. Initially focused on VLSI design and ASIC technology, it grew rapidly during the personal computer revolution of the 1980s. A significant early milestone was its 1983 initial public offering, which provided capital for expansion. Throughout the 1990s, the company shifted its strategic focus toward the burgeoning markets for enterprise storage and high-speed networking, developing critical components for hard disk drive manufacturers and telecommunications equipment vendors. This period saw it establish major design centers and manufacturing partnerships across the globe, including in Japan and Taiwan.

Products and technologies

The company's portfolio was built around several core semiconductor technologies essential for data infrastructure. Its storage solutions division produced RAID controllers and SAS expander chips used by major OEMs like Dell and Hewlett-Packard. In networking, it developed advanced network processors and traffic management chips that powered routers and switches from companies such as Cisco Systems and Juniper Networks. Another significant area was its custom integrated circuit business, which created specialized chips for clients in the consumer electronics and defense industry. Key product families included the Axxia line of communication processors and the SandForce flash memory controller technology, which was widely adopted in solid-state drives.

Acquisitions and divestitures

Growth was heavily driven by a series of strategic mergers and acquisitions. A major consolidation occurred in 2007 with the merger of the original company and Agere Systems, a spin-off from the former AT&T Bell Labs. This deal significantly expanded its intellectual property portfolio, particularly in mixed-signal integrated circuit design. Other notable acquisitions included StoreAge Networking Technologies, which added storage virtualization software, and the SandForce purchase in 2011 to bolster its solid-state drive controller business. Conversely, the company also divested non-core units, such as its military electronics business to BAE Systems and its consumer chipset operations, to sharpen its focus on enterprise and storage markets.

Corporate affairs

The company was headquartered in Milpitas, California, within the Silicon Valley region. It operated numerous research and development facilities worldwide, including significant sites in Colorado, Massachusetts, and India. For many years, Abhi Talwalkar served as its President and Chief Executive Officer, steering the company through its later strategic transformations. It was a regular participant in major industry events like the Storage Networking World conference and was a contributing member of standards bodies such as the Serial ATA International Organization and the PCI-SIG. Its corporate identity was ultimately concluded in 2014 when it was acquired by Avago Technologies in a transaction valued at approximately $6.6 billion, a deal that significantly reshaped the competitive landscape of the semiconductor industry.
