Abstract

Natural radioactivity of trace materials in the substrate which holds charge-coupled devices (CCDs) releases alpha particles that can cause soft errors in a memory. However, these errors are always in one "direction". That is, 1 becomes 0 (or 0 becomes 1, depending on the definition of the 0 and 1 states).
