Abstract
Single error correction ('SEC') code and triple error detection ('TED') code are used to optimize bandwidth and resilience under multiple bit failures. One or more errors in data stored in duplicated registers are detected and corrected using the SEC code and TED code where simultaneous read operations are produced with two copies of data for each of the duplicated registers for a multi-port banked memory array. The SEC code and TED code may be included in each of the two data copies of the simultaneous read operations.
