Original Abstract Submitted
Technology is disclosed herein for checking data integrity in a non-volatile storage system. The storage system may operate in a first mode in which a data integrity check is performed in closed blocks until more than an allowed number of word lines fail the data integrity check. After a closed block has more than the allowed number of the word lines fail the data integrity check, then the storage system may operate in a second mode in which a data integrity check is performed in open blocks. The allowed number of word lines may be equal to the number of word lines that can be recovered by XOR data in the event data is uncorrectable by an ECC engine. The data integrity check of a target word line in an open block may be performed after programming a word line adjacent to the target word line in the open block.
