Schmidt, Jack (John) D.

Biographical Notes

John (Jack) D. Schmidt joined Fairchild from the General Electric Research Laboratory in Sunnyvale, California, to work on the application of semiconductors in memory system applications in 1963. He designed discrete transistor sense and driver circuits for thin film and core memories and was involved in the design and testing of the company’s first bipolar and MOS semiconductor memory devices. Schmidt was a project engineer in a group of five technical personnel that was spun out under Harley Perkins as a group in 1965 as the Fairchild Memory Products division. He worked with Jon M. Schroeder to attach 16 of memory chips to a ceramic substrate to form a 1024-bit hybrid memory product called Semiconductor Advanced Memory (SAM). After the Memory Products division was closed he was listed on the R&D Professional Staff organizational chart in 1968 as Head of the Semiconductor Active Memory Section of the Physics Department reporting to C. Bittman. Together with Schroeder he co-founded Computer Microtechnology Inc. (CMI) in 1968 to build memory products.
