Subject: Cosmic Radiation Effects on Components
Have there been any studies or analyses on the effects of cosmic radiation on electronic components being flown at altitude? I have a system that will be flown between 45K & 50K feet comprising COTS/NDI equipment. I am particularly interested in processor and memory devices. However, any information with respect to cosmic radiation exposure and the effects on life expectancy or reliability would be appreciated.

A paper was presented at the 2000 IEEE International Reliability Physics Symposium (38th) entitled “Neutron-Induced Boron Fission as a Major Source of Soft Errors in Deep Submicron SRAM Devices” by TI, which discussed radiation testing of modern high-density low voltage memories. In addition, a number of references covering cosmic ray and alpha-particle effects on IC’s were provided. IEEE can be contacted via their web site at .
