An alpha particle striking the cell of a DRAM bit can destroy stored charge, resulting in a single bit soft error. A DRAM architecture is described that circumvents this problem by storing every DRAM bit redundantly in two cells. If a stored charge is represented by a logic 1, then when reading a DRAM bit, if either of it's cells is storing charge then the bit is a logic 1. Only if both cells of a bit have no charge is the bit a logic 0.
