Abstract
Method of operating a memory include increasing respective threshold voltages of a first subset of memory cells of a plurality of memory cells to threshold voltage levels higher than a particular voltage level in response to applying a first plurality of programming pulses, and subsequently increasing respective threshold voltages of a second subset of memory cells of the plurality of memory cells to threshold voltage levels lower than the particular voltage level in response to applying a second plurality of programming pulses, wherein the first plurality of programming pulses have respective voltage levels within a first range of voltage levels, the second plurality of programming pulses have respective voltage levels within a second range of voltage levels, and a lowest voltage level of the first range of voltage levels is lower than or equal to a highest voltage level of the second range of voltage levels.
