A Static Random Access Memory (SRAM) matrix with a read assist is described. The read assist reduces the probability associated with an SRAM matrix becoming upset by a radiation event. Each SRAM cell within the SRAM matrix includes an active delay for increasing Single Event Upset (SEU) tolerance. The described SRAM matrix also includes a read assist coupled to each column of the SRAM matrix. The read assists store values associated with a row of SRAM cells, one SRAM cell of which is to be written to. If a radiation event occurs on any of the SRAM cells not being written to, the read assist restores an original value associated with the upset SRAM cell.
