Radiation tolerant memory selection for the Mars Observer Camera
Abstract
Survey testing, using Co-60 gamma rays, of high-capacity RAM for a spacecraft image buffer has identified a candidate 1 Mb CMOS dynamic RAM device, the M411024xP from AT&T, which showed no functional degradation at 30 krad(Si), and usable performance at 100 krad(Si).
