    摘要: An embodiment of a writing system for a phase change memory based on a present application is disclosed. The writing system comprises a first phase change memory (PCM) cell, a second PCM cell, a first writing circuit and a verifying circuit. The first writing circuit executes a writing procedure, receives and writes a first data to the first PCM cell. The verifying circuit executes a verifying procedure and the circuit further comprises a processing unit and a second writing circuit. The processing unit reads and compares the data stored in the second PCM cell with a second data. The second writing circuit writes the second data to the second PCM cell when the data stored in the second PCM cell and the second data are not matched.

    摘要: Devices controlling a phase change storage element and methods for increasing reliability of a phase change storage element. The invention introduces a first operation mode and a second operation mode. A reference phase change storage element is forced a write current for an ideal conduction period in the first operation mode. In the second operation mode, the invention generates a proper conduction period based on the resistance of the reference phase change storage element, and forces the write current into the controlled phase change storage element for the proper conduction period.
