Embodiments herein describe a hardware based scrubbing scheme where correction logic is integrated with memory elements such that scrubbing is performed by hardware. The correction logic reads the data words stored in the memory element during idle cycles.

By using built-in or integrated correction logic, the embodiments herein do not add extra work for the processor, or can work with applications that do not include a processor. Further, because the correction logic scrubs the memory during idle cycles, correcting bit errors does not have a negative impact on the performance of the memory element.
