Abstract:
Apparatuses, systems, and methods for error correction for selected bit pairs. A memory device may include an error correction code (ECC) circuit which may receive data bits as part of a read or write operation and generate parity bits based on the data bits. The parity bits may be used to locate and correct errors in the data bits. The parity bits may be generated based on a syndrome value. Each of the individual data bits may be associated with a syndrome value. In addition, some selected pairs of data bits may also be associated with a syndrome value. This may allow the ECC circuit to correct errors in individual data bits or in one of the selected pairs of data bits. In some embodiments, the selected pairs may represent adjacent memory cells along a word line.
