Abstract:
Methods, systems, and devices for distribution-following access operations for a memory device are described. In an example, the described techniques may include identifying an activation of a first memory cell at a first condition of a biasing operation, and identifying an activation of a second memory cell at a second condition of the biasing operation, and determining a parameter of an access operation based at least in part on a difference between the first condition and the second condition. In some examples, the memory cells may be 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.
