A method and enhanced Static Random Access Memory (SRAM) redundancy circuit reduce wiring and the required number of redundant elements. A bitline redundancy mechanism allows the swapping of a pair of bitlines for a redundant pair of bit columns. Two of the adjacent bitlines are swapped out at a time, one even and one odd. The swap is accomplished by steering the data around the bad columns and adding redundant columns on the end that are steered in when needed.
