Abstract
A method for operating a multi-level cell ('MLC') memory array of an integrated circuit ('IC') programs first data into a first plurality of MLCs in the MLC memory array at a first programming level. Threshold voltages for the first plurality of MLCs are sensed, and an adjust code is set according to the threshold voltages. Second data is programmed into a second plurality of MLCs in the MLC memory array at a second programming level, the second plurality of MLCs having a program-verify value set according to the adjust code. In a further embodiment, a reference voltage for reading the second plurality of MLCs is set according to the adjust code.
