Abstract: The systems and methods described herein relate to a bi-directional data path (DQ) symbol map generated based on error correction operations. A device may include sub-wordline drivers and bi-directional data paths (DQs) that couple between the sub-wordline drivers and input/output (I/O) interface circuitry based on assignments indicated by the DQ symbol map. The assignments may be generated based on error correction operations performed on data of the memory bank. In particular, the DQ symbol map may be generated to avoid some conditions that, if occurring, may render one or more data errors uncorrectable. These systems and methods may reduce a likelihood of a data error associated with a DQ being uncorrectable.
