The first single chip CPU was the Intel 4004 invented in Nov 1971‚ a 4-bit processor meant for a calculator. It processed data in 4 bits‚ but its instructions were 8 bits long. Program and data were separate. In 1972‚ Texax Instruments followed the Intel 4004/4040 closely with the 4-bit TMS 1000‚ which was the first microprocessor to include enough RAM‚ and space for a program ROM‚ to allow it to operate without multiple external support chips. It also featured an innovative feature to add custom
