Abstract

An integrated circuit may have an array of memory elements. Each memory element may have multiple memory cells. Each memory element may have a voting circuit that receives signals from the memory cells in that memory element. The voting circuit can produce an output based on the signals. The signals stored by the memory cells of each memory element may be redundant so that the voting circuit can produce an accurate output even in the event that a radiation strike causes some of the memory cells to flip their states to erroneous values. The memory elements may be based on memory cells such as static random-access memory cells and thyristor-based cells.
