Updating read voltages using syndrome weight comparisons
A method performed at a data storage device includes adjusting a first read voltage and a second read voltage to form sets of read voltages. First representations of data are read from a logical page in the non-volatile memory according to the sets of read voltages. The first representations of the data correspond to multiple values of the first read voltage and the second read voltage. The first representations of the data are stored in a memory and second representations of the data are generated based on the first representations. A value of the first read voltage is selected based on syndrome weights corresponding to the second representations.
