Abstract
Methods and systems for verifying two or more programming states at the same time are described. During a program verify operation, two or more memory cell threshold voltage levels may be concurrently verified by applying a word line voltage to a plurality of memory cells, applying two or more different bit line voltages to the plurality of memory cells, and sensing the plurality of memory cells while the two or more different bit line voltages are applied to the plurality of memory cells. The bit line voltages applied during the program verify operation may allow a first set of the plurality of memory cells to be sensed at a first voltage level while a second set of the plurality of memory cells are sensed at a second voltage level different from the first voltage level.
