Abstract:
Methods, systems, and devices for improved techniques for multi-level memory cell programming are described. A memory array may receive a first command to store a first logic state in a memory cell for storing three or more logic states. The memory array may apply, as part of an erase operation, a first pulse with a first polarity to a plurality of memory cells to store a second logic state different from the first logic state in the plurality of memory cells, where the plurality of memory cells includes the memory cell. The memory array may apply, as part of a write operation or as part of the erase operation, one or more second pulses with a second polarity to the memory cell to store the first logic state in the memory cell based on applying the first pulse.
