Techniques for determining access information describing an accessing of a phase change memory (PCM) device. In an embodiment, an initial read time for a PCM cell is determined based on a final read time for the PCM cell, set threshold voltage information and a reset threshold voltage drift, wherein the final read time and the initial read time define a time window for reading the PCM cell. In another embodiment, a time window extension is determined based on a reset threshold voltage drift.
