Patent attributes
A read-disturb-based read temperature identification system includes storage device(s) that each determine read disturb information for each block in that storage device, use that read disturb information to identify a subset of rows in at least one block in that storage device that have a higher read temperature than the other rows in the at least one block in that storage device and, based on that identification, generate and store a local logical storage element read temperature map that identifies a subset of logical storage elements associated with that storage device that have a higher read temperature than the other logical storage elements associated with that storage device. A global read temperature identification subsystem coupled to the storage device(s) may then retrieve at least a portion of the local logical storage element read temperature map(s) and use them to generate a global logical storage element read temperature map.
