Logic may implement implicit integrity techniques to maintain integrity of data. Logic may perform operations on data stored in main memory, cache, flash, data storage, or any other memory. Logic may perform more than one pattern check to determine repetitions of entities within the data. Logic may determine entropy index values and/or Boolean values and/or may compare the results to threshold values to determine if a data unit is valid. Logic may merge a tag with the data unit without expanding the data unit to create an encoded data unit. Logic may decode and process the encoded data unit to determine the data unit and the tag. Logic may determine value histograms for two or more entities, determine a sum of repetitions of the two or more entities, and compare the sum to a threshold value. Logic may determine that a data unit is valid or is corrupted.
