More Information
Summary:A read-disturb-based read temperature time-based attenuation system includes a storage device that is coupled to a global read temperature identification subsystem. The storage device determines current read disturb information for data stored in a block in the storage device during a current time period, processes the current read disturb information and previous read disturb information that was determined during at least one previous time period that was prior to the current time period in order to generate a read temperature for the data stored in the block, generates a local logical storage element read temperature map that includes the read temperature, and provides the local logical storage element map to the global read temperature identification subsystem.
