1. An amplification-based read disturb information determination system, comprising:
a global read temperature identification subsystem; and
a storage device that is coupled to the global read temperature identification system and configured to:
amplify data errors in a first row in a storage subsystem in the storage device by shifting a first value voltage reference level associated with the first row to provide a second value voltage reference level;
read, from the first row in the storage subsystem in the storage device,
data stored in bits provided in the first row in the storage subsystem in the storage device, and error correction information associated with the data;
identify, using the error correction information, a number of the bits that store portions of the data with errors;
determine, for the first row in the storage subsystem in the storage device based on the number of bits that store portions of the data with errors, read disturb information;
generate, using the read disturb information, a read temperature for a second row in the storage subsystem in the storage device; and
provide the read temperature to the global read temperature identification system.
