  • Patent number: 8427894
    Abstract: A method and a dynamic Static Random Access Memory (SRAM) circuit for implementing single bit redundancy with any bit decode, and a design structure on which the subject circuit resides are provided. The SRAM circuit includes a plurality of bitline columns and a pair of redundancy columns respectively coupled to a respective merged bit column select and redundancy steering multiplexer. Each merged bit column select and redundancy steering multiplexer receives a respective select signal input. A select signal generation circuit receives a redundancy steering signal and a respective one-hot bit select signal, generating the respective select signal input.
    Type: Grant
