This invention relates generally to Static Random Access Memory (SRAM) cells and more particularly, relates to a SRAM cell wherein soft-error due to .alpha.-particle radiation is reduced by permitting the potential at the common-emitter node of the cross-coupled transistors of the memory cell to swing freely. Still more particularly, it relates to a SRAM cell wherein the common-emitter node of the cell is decoupled from a heavily capacitively loaded word line with its common constant current source by means of a constant current source or current mirror disposed in each cell between the common-emitter node and the word line.
