    摘要: One embodiment of the invention relates to a method for conditioning resistive memory cells of a memory array with a number of reliable resistance ranges, where each reliable resistance range corresponds to a different data state. In the method, group of at least one resistive memory cell is accessed, which group includes at least one unreliable cell. At least one pulse is applied to the at least one unreliable cell to shift at least one resistance respectively associated with the at least one unreliable cell to the highest of the reliable resistance ranges. Other methods and systems are also disclosed.

    摘要: An integrated circuit includes an array of resistive memory cells having varying critical dimensions and a write circuit. The write circuit is configured to reset a selected memory cell by applying a first pulse having a first amplitude and a second pulse having a second amplitude less than the first amplitude to the selected memory cell.
