Abstract
The threshold voltage range of a multilevel memory cell may be increased without using a negative voltage pump. In one embodiment, an added positive voltage may be applied to the source of the selected cell. A boost voltage may be applied to the output of a sense amplifier. Non-ideal characteristics of a buffer that supplies the voltage to the selected cell may be compensated for in some embodiments.
