Abstract
A memory device, such as a MRAM device, includes a plurality of memory macros, where each includes an array of memory cells and a first ECC circuit configured to detect data errors in the respective memory macro. A second ECC circuit that is remote from the plurality of memory macros is communicatively coupled to each of the plurality of memory macros. The second ECC circuit is configured to receive the detected data errors from the first ECC circuits of the plurality of memory macros and correct the data errors.
