Abstract

A single event upset (SEU) tolerant SRAM bit cell for six-transistor (6T), eight-transistor (8T), or multi-port RAM cell configurations fabricated in accordance with 0.18 &mgr;m or smaller CMOS processes. SEU tolerance is achieved without significantly increasing the cell's read and write cycle time and negligible impact on cell stability.
