Abstract
Read Apparent Voltage (RAV) is an anomality in which an apparent threshold voltage of a storage cell transistor does not equal the actual threshold voltage of that same transistor by a large enough magnitude that the binary state of transistor is not read correctly. An infector page may cause the RAV anomality within a different infected page. To determine whether any page is an infector, each page is programmed, a page within each block is read, an acting infector page within an acting infector block is set, a possible infected page within a possible infected block is set, the acting infector page is read a predetermined plurality of instances, the possible infected page is read, a raw bit error rate (RBER) of the read of the possible infected page is determined, and the acting infector page is set as an actual infector page based upon the determined RBER.
