Abstract
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.
