History.
Alchemy Semiconductor was a fabless semiconductor company based in Austin, Texas and founded in May 2000. They purchased a license for the MIPS architecture#MIPS32 instruction set from MIPS Technologies and developed the Au1 microprocessor and the Au1000 and Au1550 SoCs.
Alchemy Semiconductor was acquired by AMD in 2002, which in Summer 2006 sold the Alchemy processor line to Raza Microelectronics. In December 2007, Raza Microelectronics changed its name to RMI Corporation. In June 2009, NetLogic Microsystems acquired RMI for $183.4 million in stock. In September 2011, Broadcom acquired all NetLogic shares in a transaction valued around $3.7bn.
