Abstract: The various implementations described herein include systems, methods and/or devices that may enhance the reliability with which data can be stored in and read from a memory. The method includes, in response to one or more host read commands, reading data from a set of memory cells in a flash memory array in accordance with a first reading threshold voltage and performing an error correction process on the read data to produce error correction information. The method further includes determining, based on the error correction information, whether to adjust the first reading threshold voltage, and upon determining to adjust the first reading threshold voltage, setting the value of the first reading threshold voltage to a value greater or less than a current value of the first reading threshold voltage. In some implementations, the method further includes initiating a recalibration of the first reading threshold voltage when a predefined condition occurs.
