Zusammenfassung:Disclosed in some examples are methods, systems, devices, and machine-readable mediums for compensating for charge loss effects. In some examples, a charge loss may be estimated by a charge loss monitor for a particular unit of a NAND device and may be utilized to select a charge loss compensation scheme. The charge loss may be estimated by the charge loss estimation process by determining a reference read voltage and calculating a bit count resulting from a read at that reference read voltage. The number of bits returned may be used to select the particular charge loss compensation scheme.
