Maximizing the Number of Threshold Logic Functions Using Resistive Memory

A new method to implement threshold logic functions using memristors is presented. This method benefits from the high range of memristor's resistivity, which is used to define different weight values, and reduces significantly the transistor count. When considering an upper bound on transistor count, the proposed approach implements many more functions as threshold logic gates when comparing to existing implementations. Experimental results in 45-nm technology show that the proposed memristive approach implements threshold logic gates with less area and power consumption.
