Compléter 4004 first microprocessorVersion en ligne complete the text using the words in the correct order par Adrian Garcia 1 ZiLOG integrated architectural implementation circuit semiconductors Shima However microprocessors microprocessor methodology technology 4004 The was launched in a 16 - pin CERDIP package on November 15 , 1971 . The 4004 was the first computer processor designed and manufactured by Intel chip maker , who previously made memory chip . Marcian " Ted " Hoff formulated the proposal in 1969 . , the microprocessor only began in 1970 when Federico Faggin was employed by Intel , from Fairchild Semiconductor , to direct the project and to design the 4004 ( 1970 - 1971 ) . , Faggin had developed the pioneering technology called Silicon Gate Technology ( SGT ) and had also designed the first MOS using SGT technology ( the Fairchild 3708 ) , in 1968 , demonstrating the viability of the new . As soon as he started working for Intel , Faggin created a new " random logic design " with silicon gate , which did not exist previously , and used it to fit the microprocessor into a single chip . Its methodology was used in all of Intel's first designs ( 8008 , 4040 , 8080 ) . Masatoshi of Busicom assisted Faggin during the development of the 4004 family and later wrote the software for the Busicom calculator . Shima joined the company , the first company dedicated exclusively to , founded by Federico Faggin in late 1974 , and developed the design of the Z80 with Faggin .
