An amplification-based read disturb information determination system includes a storage device coupled to a global read temperature identification system. The storage device amplifies data errors in a first row in its storage subsystem by shifting a first value voltage reference level associated with the first row to provide a second value voltage reference level, reads data stored in bits provided in the first row and error correction information associated with the data, and uses the error correction information to identify a number of the bits that store portions of the data with errors. For the first row and based on the number of bits that store portions of the data with errors, the storage device determines read disturb information and uses it to generate a read temperature for a second row in its storage subsystem that it provides to the global read temperature identification system.
