Once … Webread latency in the order of SLC’s. In order to avoid extra writes onto memory cells as a result of striping memory lines, the proposed design uses a pairing write queue to synchronize write-back requests associated with blocks that are paired in striping mode. Our evaluation shows that our design signifi-cantly improves the average memory ...
