ABSTRACT:
Generation of a random sequence using alpha particle emissions is described. A device includes memory cells, an alpha particle emitter, and read circuitry. The memory cells are sensitive to alpha particle emissions. The alpha particle emitter is proximate to the memory cells for changing state of one or more bits of the memory cells within a period of time. The read circuitry is coupled to the memory cells and configured to periodically issue a read command to periodically read the memory cells.
