In the 1980s it was recognized that integrated circuit (IC) obsolescence threatened military readiness. To provide a solution the Sarnoff Corporation, with the Defense Logistics Agency (DLA) and the Defense Supply Center Columbus, developed the Generalized Emulation of Microcircuits (GEM) program. 

Using on-site design, test and flexible foundry capabilities, the Sarnoff Corporation provides a continuing source of form, fit, function, and interface (F3I) replacements for non-procurable microcircuits. Devices are supplied to existing system documentation and meet the specifications of the original devices, including physical, electrical, quality and environmental parameters. Over 735 part types have been emulated in support of military and commercial platforms.

These include parts from bipolar and MOS microcircuit technology families ranging from single function complexities to small microprocessors. Using GEM die, Sarnoff can also support turnkey hybrid requirements.

Sarnoff is QML certified to MIL-PRF-38535 ensuring compliance to SMD class Q and MIL-M/38510 class B devices. Parts are fully traceable and delivered with a certificate of conformance to customer procurement requirements.
