Abstract
A memory array operates as an alpha particle detector. A predetermined state is stored in each memory storage location. The operating voltage of the memory array is established at a voltage where the stored values are relatively stable and not subject to change except as a result of alpha particle impingement. Impinging alpha particles are detected by the state changes they cause in the memory storage locations.
