Abstract

A programming operation for a set of non-volatile storage elements determines whether the storage elements have been programmed properly after a program-verify test is passed and a program status=pass is issued. Write data is reconstructed from sets of latches associated with the storage elements using logical operations optionally one or more reconstruction read operations. Normal read operations are also performed to obtain read data. A number of mismatches between the read data and the reconstructed write data is determined, and determination is made as to whether re-writing of the write data is required based on the number of the mismatches.
