A detailed history of LSI Logic, from its founding by Wilfred Corrigan after leaving Fairchild Semiconductor, to becoming a leader in the ASIC industry, and its eventual decline and acquisition by Avago.
Summary
- Wilfred 'Wilf' Corrigan founded LSI Logic after leaving Fairchild Semiconductor, leveraging his industry experience.
- LSI Logic, a pioneer in ASICs, grew rapidly in the 1980s, becoming a major player in the semiconductor industry.
- The company faced a decline due to competition from FPGAs, the emergence of VLSI, and the rise of silicon foundries like TSMC.
- After several strategic shifts and layoffs, LSI Logic was finally acquired by Avago (now Broadcom) in 2013 for $6.6 billion.
Chapter 1
LSI Logic's origins and Wilf Corrigan's journey from Liverpool to founding the company.
- Wilf Corrigan, born to a dockworker in Liverpool, entered the semiconductor industry through Transistron and Motorola.
- He moved to Fairchild Semiconductor, becoming CEO and witnessing the exodus of key talent to Intel and AMD.
- After Fairchild's acquisition by Schlumberger, Corrigan left and contemplated starting his own company.
Chapter 2
The early days of integrated circuits at Fairchild and the concept of custom chips.
- In the mid-1960s, customers requested customized integrated circuits from Fairchild, which was initially uneconomical.
- Gordon Moore postulated the increase in components on an IC, hinting at the need for specialized, low-volume chips.
- Fairchild's CAD group created the first EDA system, aiding the design of custom chips like the Micromosaic.
Chapter 3
The struggles of Fairchild's custom chips team and changes in the semiconductor market.
- Fairchild's custom chips division faced financial difficulties and conservative management under 'Hogan's Heroes'.
- The introduction of microprocessors by Intel led to the closure of the custom chips team.
- The 1970s brought about changes: CAD software, CMOS technology, and a glut of semiconductor fabs.
Chapter 4
The foundation of LSI Logic and its growth strategy.
- Corrigan reassembled the Fairchild team to co-found LSI Logic.
- The company raised $6 million in initial funding and chose a fabless model, creating masterslices for customization.
- LSI Logic's first customer was 3H, and they partnered with Toshiba for CMOS manufacturing.
Chapter 5
LSI Logic's rapid growth, IPO, and international expansion.
- LSI Logic grew rapidly with major customers like DEC, and went public in 1983 on NASDAQ.
- The ASIC market grew to 10% of the semiconductor industry, with LSI holding significant market share.
- LSI expanded globally by creating subsidiaries in Japan and Europe, which operated almost like startups.
Chapter 6
The decline of the ASIC industry and LSI Logic's challenges.
- The rise of VLSI and standard cell design, along with the emergence of FPGAs, eroded LSI's market.
- Silicon foundries like TSMC reduced the need for intermediary companies in custom chip production.
- LSI Logic faced financial difficulties and began a strategic shift to survive in the changing industry.
Chapter 7
LSI Logic's transformation, layoffs, and eventual acquisition by Avago.
- LSI Logic laid off employees and exited Sematech as part of restructuring efforts.
- The company survived by transitioning to new business areas and focusing on data centers and mass storage.
- In 2013, LSI Logic was acquired by Avago for $6.6 billion, leveraging its strengths for further growth.
Chapter 8
The lasting impact of LSI Logic on the semiconductor industry and its employees.
- Former LSI Logic employees reflect on their experiences and the company's impact.
- LSI Logic is largely forgotten but played a crucial role in the development of the fabless semiconductor model.
- Notably, Jensen Huang worked at LSI Logic before founding Nvidia, gaining valuable industry experience.
