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 a plurality of possible data states by applying a voltage pulse to the memory cell, determining the memory cell snaps back in response to the applied voltage pulse, turning off a current to the memory cell upon determining the memory cell snaps back, and applying a number of additional voltage pulses to the memory cell after turning off the current to the memory cell.

Abstract: Methods, systems, and devices for adaptive write operations for a memory device are described. In an example, the described techniques may include identifying a quantity of access operations performed on a memory array, modifying one or more parameters for a write operation based on the identified quantity of access operations, and writing logic states to the memory array by performing the write operation according to the one or more modified parameters. In some examples, the memory array may include memory cells associated with a configurable material element, such as a chalcogenide material, that stores a logic state based on a material property of the material element. In some examples, the described techniques may at least partially compensate for a change in memory material properties due to aging or other degradation or changes over time (e.g., due to accumulated access operations).
