Mostek

Mostek was an integrated circuit manufacturer, founded in 1969 by ex-employees of Texas Instruments. Initially their products were manufactured in Worcester, Massachusetts, however by 1974 most of its manufacturing was done in the Carrollton, Texas facility on Crosby Road. Mostek produced one of the first single-chip calculator circuits for Nippon Calculating Machine in 1970. Development of a small die size 4K device in 1973 established the company as a major DRAM supplier. United Technologies Corporation purchased the company in 1979 and sold the business to SGS-Thomson in 1987.
