Summary:ECC (error checking and correction) can be extended to allow an ECC code to correct memory subarray errors. A memory device includes multiple input/output (I/O) connectors to interface with an external device such as a controller. The memory device includes multiple arrays or subarrays that are specifically mapped to I/O connectors instead of arbitrarily routed. As such, the data paths of the memory subarrays can be exclusively routed to a specific I/O connector. The I/O connector can be uniquely associated with a single memory subarray, or multiple memory subarrays can be mapped to a specific I/O connector. The mapping is in accordance with an error checking and correcting (ECC) code matrix, where a code of the ECC code matrix corresponding to the specific I/O connector is to check and correct data corruption errors and I/O errors for the associated one or multiple memory subarrays.
