Abstract
A user selectable option to a memory cell, such as a multilevel NAND flash cell, that allows the user to select to optimize programming time or the data integrity. A programmable memory cell can have multiple programming modes. A mode selector can switch the programming of each cell or group of cells between the programming modes. A first programming mode can program the cell with a first programming voltage and maintaining at least a fifty percent of the maximum data margin. A second programming mode can program the cell with a second programming voltage and maintaining at least an eighty five percent of the maximum data margin. The first programming voltage can be greater than the second programming voltage.
