Abstract
In accordance with exemplary embodiments, a multi-level flash memory employs error correction of systematic errors when reading multi-level flash memory. Error correction includes i) detection of each systematic error, ii) feedback of the systematic error to circuitry within the memory, and iii) subsequent adjustment within that circuitry to cause a correction of systematic error in the output signal of the multi-level flash memory.
