Classification: CPC G | IPC G

Claim 0:
1. A read-disturb-based logical storage read temperature information maintenance 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:
identify, from a first physical block in that storage device, current read disturb information associated with a first row provided by the first physical block in that storage device;
map the current read disturb information to one or more logical storage elements included in a logical-to-physical storage element mapping for that storage device along with previous read disturb information that was previously mapped to the one or more logical storage elements included in the logical-to-physical storage element mapping for that storage device;
generate, based on the current read disturb information and the previous read disturb information mapped to the one or more logical storage elements included in the logical-to-physical storage element mapping for that storage device, a current local logical storage element read temperature map; and
provide the current local logical storage element read temperature map to the global read temperature identification subsystem.
