Abstract:
The present disclosure includes apparatuses, methods, and systems for multi-state programming of memory cells. An embodiment includes a memory having a plurality of memory cells, and circuitry configured to program a memory cell of the plurality of memory cells to one of four possible data states by applying a first voltage pulse to the memory cell wherein the first voltage pulse has a first polarity and a first magnitude, and applying a second voltage pulse to the memory cell wherein the second voltage pulse has a second polarity and a second magnitude, and the second voltage pulse is applied for a shorter duration than the first voltage pulse.
