Monolithic Memories, Inc. (MMI) produced bipolar PROMs, programmable logic devices, and logic circuits (including 7400 series TTL).

A team of MMI engineers,under the direction of Ze'ev Drori and headed by John Birkner and H. T. Chua, invented the class of devices known as Programmable Array Logic (PAL).

MMI was founded in 1969 by former Fairchild Semiconductor engineer Ze'ev Drori, later the President and CEO of Tesla Motors. In 1987, under the stewardship of President Irwin Federman, it was merged with Advanced Micro Devices in a $442 million stock swap[1] to become the world's largest integrated circuit manufacturer.[2] AMD later spun off their programmable logic division as Vantis, which was then acquired by Lattice Semiconductor.
