摘要： A memory array with write feedback includes a number of row lines intersecting a number of column lines, a memory element connected between one of the row lines and one of the column lines, an electrical condition supply to be selectively applied to one of the row lines; and a feedback control loop to control an electrical condition supplied by the electrical condition supply. A method for setting the state of a memory element within a memory array includes applying an electrical condition to the memory element within the memory array, sensing a resistive state of the memory element, and controlling the electrical condition based on the sensed resistive state to cause the memory element to reach a target resistance.

摘要： A method of switching a memristive device in a two-dimensional array senses a leakage current through the two-dimensional array when a voltage of half of a switching voltage is applied to a row line of the memristive device. A leakage compensation current is generated according to the sensed leakage current, and a switching current ramp is also generated. The leakage compensation current and the switching current ramp are combined to form a combined switching current, which is applied to the row line of the memristive device. When a resistance of the memristive device reaches a target value, the combined switching current is removed from the row line.
