Abstract
A solid-state device having a substrate that receives an ionizing radiation, logic circuits, integrity circuits, and a collection circuit. The logic circuits are operational to perform logic functions. The logic circuits are located in an area on the substrate, and are individually susceptible to a possible corruption by the ionizing radiation. Each integrity cell is initialized to a predetermined state. The integrity cells are located in the area on the substrate, arranged in a pattern neighboring the logic circuits, and individually susceptible to disrupting the predetermined state in response to the ionizing radiation. The collection circuit is located on the substrate. The collection circuit is operational to read the plurality of integrity cells, and assert a report signal that identifies the possible corruption in a subset of the logic circuits due to the ionizing radiation in response to reading an incorrect state in a neighboring one of the integrity cells.
