Abstract
In various embodiments, the reference voltage used for read operations in a non-volatile memory may be adjusted up or down in an attempt to read data from an area that previously produced at least one uncorrectable error. The direction and amount of this adjustment may be based on the number and direction of correctable errors in surrounding data.
