Abstract
Example methods, apparatus, and articles of manufacture to perform error detection and correction are disclosed. A disclosed example method involves enabling a memory controller to operate in one of a tagged memory mode or a non-tagged memory mode. In addition, when the tagged memory mode is enabled in the memory controller, a five-error-correction-six-error-detection per-burst mode is selected to perform error correction on data. When the non-tagged memory mode is enabled in the memory controller, one of a six-error-correction-seven-error-detection per-burst mode or a single-error-correction-dual-error-detection per-transfer mode is selected based on a pattern of error types in the data.
