摘要:
One embodiment of the invention relates to a method for repairing a memory array. In the method, a group of at least one memory cell is dynamically analyzed to determine whether the memory array includes at least one faulty cell that no longer properly stores data. If the group includes at least one faulty cell, at least the at least one faulty cell is associated with at least another cell. Other methods, devices, and systems are also disclosed.

A memory includes a bit line and a plurality of resistive memory cells coupled to the bit line. Each resistive memory cell is programmable to each of at least three resistance states. The memory includes a first resistor for selectively coupling to the bit line to form a first current divider with a selected memory cell during a read operation.

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.

An integrated circuit includes a resistance changing memory element and a circuit. The circuit is configured to program the memory element by iteratively applying a variable program pulse to the memory element until a resistance of the memory element crosses a first reference resistance. The variable program pulse is adjusted for each iteration such that the resistance of the memory element approaches the first reference resistance.
