Abstract
Embodiments of the present invention include a crossbar array that includes a resistive processing unit (RPU) device at each crosspoint in the crossbar array. The RPU device includes a single weight storage element, and multiple weight reader elements. A first weight reader element is coupled with a first row wire to compute a first matrix product value using a first value and a stored value, the first value being transmitted via the first row wire and the stored value being stored in the single weight storage element. A second weight reader element is coupled with a second row wire to compute a second matrix product value of a second value and said stored value, the second value being transmitted via the second row wire.
