Abstract
According to one aspect, bank-level fault management in a memory system is provided. The memory system includes a plurality of ranks, each rank including memory devices each having a plurality of banks. A first error is detected in a first bank number of a first memory device of a rank. The first bank number of the first memory device is marked with a bank-level chip mark. The bank-level chip mark isolates declaration of an error condition to the first bank number. A second error is detected in the first bank number of a second memory device of the rank. Access requests for the first bank number of the second memory device are steered to the non-faulty bank having the second bank number. A bank-level fault management action is performed based on the bank-level chip mark to accommodate the error condition by correcting the first error using an error-correcting code decoder.
