Abstract
A method of obtaining a dot product includes applying a number of first voltages to a corresponding number of row lines within a memristive cross-bar array to change the resistive values of a corresponding number of memristors located a junctions between the row lines and a number of column lines. The first voltages define a corresponding number of values within a matrix, respectively. The method further includes applying a number of second voltages to a corresponding number of the row lines within the memristive cross-bar array. The second voltages define a corresponding number of vector values. The method further includes collecting the output currents from the column lines. The collected output currents define the dot product.
