Abstract

This paper discusses scaled simulated space radiation experiments performed at the White Sands Missile Range as part of the Microelectronics Testing and Technology Obsolescence Program, (METTOP) at New Mexico Tech Energetic Materials Research and Testing Center (EMRTC). Total dose Gamma exposure effects are observed on a split gate cell technology EEPROM device. The data shows that on all device pins most DC electrical parametrics, such as opens, shorts, input and output leakage currents, continue to perform at normal pre-event levels but with significant bitmap, memory cell and functional post event failures.
