Abstract:
A read disturb information isolation system includes a storage subsystem including a plurality of blocks that each include a plurality of rows, and a read disturb information isolation subsystem that is coupled to the storage system. For at least one of the plurality of blocks, the read disturb information isolation system retrieves data from at least a subset of rows in that block, identifies read disturb information for that data, performs at least one isolation operation on that read disturb information to generate isolated read disturb information, and provides that isolated read disturb information to a read temperature identification subsystem. The read temperature identification subsystem may then use the isolated read disturb information provided by the read disturb information isolation subsystem to generate a local logical storage element read temperature map.
