Investigation of Heavy Particle Induced Latch-Up, Using a Californium-252 Source, in CMOS SRAMs and PROMs

Abstract
Heavy ion-induced latch-up, in commercial CMOS SRAMs and PROMs, was examined using a laboratory Californium-252 source, in order to simulate the cosmic environment. The ability to use the CASE system (Californium-252 Assessment of Single-event Effects) enabled detailed electrical measurements to be made of the devices in the latched condition.
