Abstract:
1. A non-transitory computer readable medium that stores instructions for: performing a shortened read attempt of data and redundant information to provide an estimate of the data and an estimate of the redundant information; wherein the shortened read attempt has a duration that is shorter than a duration of a full read attempt; processing the estimation of the data to provide a first signature; processing the estimation of the redundant information to provide a second signature; comparing the first signature to the second signature; and providing the estimate of the data as a read result if the first and second signatures equal each other; wherein errors introduced by the shortened read attempt of the data only result in an over-estimation of an amount of charge stored in memory cells that store the data; whereon errors introduced by the shortened read attempt of the redundant information only result in an under-estimation of the amount of charge stored in the memory cells that store the data.
