Wear counts of all active erase-units (containing client data) and free erase-units (not containing client data) are tracked. Wear counts are used to determine low-wear active erase-units having relatively low wear counts and high-wear free erase-units having relatively high wear counts. In some embodiments, data contents of low-wear active erase-units are transferred to high-wear free erase-units, whereby the low-wear active erase-units are converted to free erase-units and may later store different client data which may increase the current rate of wear for the erase-unit. The high-wear free erase-units are converted to active erase-units that store client data that is infrequently erased/written, which may reduce the current rate of wear for the erase-unit. As such, wear is spread more evenly among erase-units of the LLRRM device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wear leveling for low-wear areas of low-latency random read memory","description":"Described herein are method and apparatus for performing wear leveling of erase-units of an LLRRM device that considers all active erase-units.
