The 4004's architecture laid the foundation for subsequent Intel processors, including the improved Intel 4040, released in 1974, and the 8-bit Intel 8008 and 8080.

The Intel 4004 is widely considered to be the world's first general-purpose CPU-on-a-chip. But there were pioneers of LSI technology at other companies who also deserve credit for their work.

Intel repurchased the rights to the 4004 from Busicom for a fraction of the device’s eventual value. The 4004 would be one of the most important conceptual breakthroughs of the 1900s: a programmable …

The birth of the 4004 was an intense moment witnessed by Faggin alone, working into the night in the deserted Intel labs. He had received the 4004 wafers from the manufacturing line at around 6 PM, in …
