Investigation Of Ge2Te2Sb5 Chalcogenide Thin Film For Use As An Analog Memory, Travis F. Blake

Theses and Dissertations

This work investigates the feasibility of using Ge₂Te₂Sb₅ chalcogenide films for analog memory. Thick film chalcogenide memory devices provided by Ovonyx, Inc. are characterized to determine how well the devices meet the repeatability, stability and predictability criteria needed to accurately store analog data values. Chalcogenide memory devices take advantage of the phase-shifting nature of chalcogenide materials to store the analog data as a resistance level. An automated test system was developed to characterize the material and the prototype devices with the goal to determine the 1) non-destructive readability of the device at different resistance values; …
