Classification: CPC G | IPC G

Claim 0:
1. A read-disturb-based physical storage read temperature information identification system, comprising:
a global read temperature identification subsystem; and
at least one storage device coupled to the global read temperature identification subsystem, wherein each at least one storage device is configured to:
read, from at least one physical block in that storage device, valid data and obsolete data;
identify, based on the reading of the valid data and the obsolete data from the at least one physical block in that storage device, read disturb information associated with each row provided by the at least one physical block in that storage device;
generate, using the read disturb information associated with each row provided by the at least one physical block in that storage device, a local logical storage element read temperature map for that storage device; and
provide the local logical storage element read temperature map to the global read temperature identification subsystem.
