description Ted Hoff Overview

Ted Hoff is an American electrical engineer who, while working at Intel in 1971, collaborated with Federico Faggin and Stanley Mazor to develop the Intel 4004 microprocessor. The 4004 was the first commercial single-chip microprocessor, containing approximately 2,300 transistors on a chip measuring 3 x 4 millimeters. This breakthrough technology initially designed for Busicom calculators ultimately enabled the development of programmable computing devices.

help Ted Hoff FAQ

What is Ted Hoff's most famous invention?

Ted Hoff is renowned for collaborating with Federico Faggin and Stanley Mazor to develop the Intel 4004 microprocessor. Released in 1971, the 4004 was the first commercial single-chip microprocessor in the world.

How many transistors were inside the Intel 4004 designed by Ted Hoff's team?

The Intel 4004 contained approximately 2,300 transistors on a single silicon chip. This incredibly low density is a stark contrast to modern processors, which contain billions of transistors.

What specific problem was Ted Hoff trying to solve when he created the microprocessor?

Hoff proposed the architecture for a general-purpose programmable logic chip to replace a complex array of custom-designed integrated circuits. The original request came from the Japanese calculator company Busicom, which wanted dedicated chips for their new printing calculator.

Where did Ted Hoff work when he invented the microprocessor?

He was working as an electrical engineer at Intel Corporation in Santa Clara, California. He was employee number 12 at the then-fledgling technology company, which was primarily focused on manufacturing semiconductor memory.
