摘要:
At least one refresh without scrubbing is performed on a corresponding portion of the memory device with a first frequency. In addition, at least one refresh with scrubbing is performed on a corresponding portion of the memory device with a second frequency less than the first frequency. Accordingly, refresh operations with data scrubbing are performed to prevent data error accumulation. Furthermore, refresh operations without data scrubbing are also performed to reduce undue power consumption from the data scrubbing.
