AMD's long-running 1987 arbitration lawsuit against Intel was settled in 1995, and AMD gained access to Intel's 80486 microcode. This led to the creation of two versions of AMD's 486 processor one reverse-engineered from Intel's microcode, while the other used AMD's microcode in a clean-room design process. However, the settlement also concluded that the 80486 would be AMD's last Intel clone.
