Abstract

A memory device to determine a voltage window to read soft bit data. For example, in response to a read command, the memory device can read a group of memory cells at a plurality of test voltages to determine signal and noise characteristics, which can be used to determine an optimized read voltage for reading hard bit data and a voltage window between a first voltage and a second voltage for reading soft bit data. The soft bit data identifies exclusive or (XOR) of results read from the group of memory cells at the first voltage and at the second voltage respective. The memory device can provide a response to the read command based on the hard bit data and the soft bit data.
