LSI Logic Corporation, was an American company founded in Santa Clara, California, was a pioneer in the ASIC and EDA industries.

[6] LSI Logic Corporation was incorporated in November 1980 [7] by Wilfred J. Corrigan and began operating in early 1981 using leased facilities in Santa Clara, California.

The initial plan called for a line of CMOS gate arrays created from “masterslices” which were uncommitted transistors customized to a specific application by the deposition of unique metal interconnections.

In 1985, the firm entered into a joint venture called Nihon Semiconductor, Inc. together with Kawasaki Steel—Japan's third largest steel manufacturer—to build a $100 million wafer fabrication plant in Tsukuba, Japan.

[17] In July 1991, LSI Logic entered into an agreement with Sanyo Electric of Japan to make a set of chips that translate an HDTV signal into a television image.

[20] In 1993, Sony Computer Entertainment chose LSI Logic as their ASIC partner, charged with fitting the PlayStation CPU on a single chip.

[30] Included in this deal, LSI received AMI's MegaRAID software intellectual property, host bus adapter products and 200 RAID employees.

[33] The Engenio division of LSI Logic filed for its own IPO in 2004, but withdrew citing adverse market conditions after the burst of the dot-com bubble.

[5][40] March 2007, LSI Logic acquired SiliconStor Inc., a provider of semiconductor solutions for enterprise storage networks, for approximately $55 million in cash.

[42] August 2007, LSI Corporation signed an agreement with STATS ChipPAC Ltd to sell its Pathumthani, Thailand semiconductor assembly and test operations for $100 million.

[44] October 2007 LSI Corporation completed its sale of its Mobility Division to Infineon Technologies AG (Munich) for €330 million in cash.

[47] March 2011, LSI Corporation announced its sale of its Engenio external storage systems business to NetApp for $480 million in cash.

[1] January 2012, LSI Corporation completed the acquisition of SandForce, which produced flash memory controllers (for $370 million reported in October 2011).

[48] LSI started producing its own PCIe cards for data center servers, using SandForce's flash controller chips, under their new Nytro product line that April.
