Abstract
A device, a computer readable medium and a method that may include performing a shortened read attempt of multiple data memory cells that store data to provide an estimate of the data; wherein the shortened read attempt has a duration that is shorter than a duration of a full read attempt; performing a shortened read attempt of redundant memory cells that store redundant information to provide an estimate of the redundant information; wherein the estimate of the redundant information is indicative of an expected number of data memory cells that store a certain logic value; determining, based on the estimate of the data, an estimated number of data memory cells that store the certain logic value; comparing the expected number to the estimated number; and providing the estimate of the data as a read result if the expected number and the estimated number equal each other.
