Nonvolatile memory cross-bar array

A non-transitory computer readable medium comprising computer executable instructions stored thereon that, when executed by a processor, cause the processor to:

• control a first set of controls and a second set of controls of a nonvolatile memory cross-bar array to:
• receive a number of programming signals, the programming signals defining a number of matrix values;
• and
• receive a number of vector signals, the vector signals defining a number of vector values to be applied to the first set of controls and the second set of controls;
• and
• calculate a sum of a first dot product and a second dot product using currents collected respectively from the first set of controls and the second set of controls, the currents corresponding to the matrix values and the vector values,
• wherein the nonvolatile memory cross-bar array includes a number of junctions formed by a number of row lines intersecting a number of column lines, the first set of controls at a first set of the junctions coupling between a first set of the row lines and a first set of the column lines, the second set of controls at a second set of the junctions coupling between a second set of the row lines and a second set of the column lines, each column line including a junction of the first set of controls and a junction of the second set of controls in two different row lines, and each control of the first set of controls and the second set of controls including a transistor and a resistive memory element.
