Abstract
A method of controlling a reference cell in a resistive memory to identify values stored in a plurality of memory cells is provided. The method includes writing a first value to the plurality of memory cells, providing, to the reference cell, monotonically increasing or monotonically decreasing reference currents. The method includes reading the plurality of memory cells as each of the reference currents is provided to the reference cell, and determining a read reference current based on an aggregation of results of the reading.
