发明名称 Apparatus and methods for generating row-specific reading thresholds in flash memory
摘要 A method for generating a set of at least one row-specific reading threshold for reading at least portions of pages of data within an erase sector of a flash memory device, the method comprising predetermining at least one initial reading threshold; performing the following steps for at least one current logical page: generating bit error characterizing information regarding at least one corresponding bit error within at least one cell representing at least a logical portion of at least one successfully reconstructed previous logical page; and computing at least one row-specific reading threshold based on said bit error characterizing information and on a previous threshold initially comprising said initial threshold and subsequently comprising a row-specific reading threshold computed for a successfully reconstructed previous logical page; and reading at least a portion of said current logical page using said at least one row-specific reading threshold.
