Abstract
Described are systems and methods for memory read threshold tracking based on memory device-originated metrics characterizing voltage distributions. An example memory device includes: a memory array having a plurality of memory cells and a controller coupled to the memory array. The controller is to perform operations including: receiving a first value of a metric characterizing threshold voltage distributions of a subset of a set of the plurality of memory cells; determining a first voltage threshold adjustment value; receiving a second value of the metric; determining a second voltage threshold adjustment value; and applying the second voltage threshold adjustment value for reading the set of the plurality of memory cells.
