Abstract: This disclosure is directed to a system for performing read error handling. The system tracks read count and temperature data for a portion of a memory device and, in response to determining that the read count for the portion transgresses a threshold, compares a current bin assignment that specifies a first set of read threshold offsets for reading data from the portion of the memory device with a target bin specified in a predefined table of bin assignments.
