ABSTRACT:
Memory devices and methods are disclosed, such as those facilitating a data conditioning scheme for multilevel memory cells. For example, one such memory device is capable of inverting the lower page bit values of a complete page of MLC memory cells when a count of the lower page data values is equal to or greater than a particular value or a comparison of current levels compared with a reference current level is equal to or exceeds some threshold condition. Memory devices and methods are also disclosed providing a means for determining initial programming pulse conditions for a population of memory cells based on the number of lower page data values being programmed to a logical 0 or a logical 1 data state.
