A controller circuit is coupled to the bottom and top electrodes and is configured to perform a first reset operation by applying a signal at a first amplitude across the PCM layer for a first time period and decreasing the signal from the first amplitude to a second amplitude for a second time period; and to perform a second reset operation by applying the signal at a third amplitude across the PCM layer for a third time period and decreasing the signal from the third amplitude to a fourth amplitude for a fourth time period greater than the second time period. After the fourth time period, the PCM layer has a percent crystallinity greater than the PCM layer after the second time period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PCRAM analog programming by a gradual reset cooling step","description":"In some embodiments, the present disclosure relates a phase change random access memory device that includes a phase change material (PCM) layer disposed between bottom and top electrodes.
