Title: Compensating for parasitic voltage drops in circuit arrays

Abstract

Various technologies for improving uniformity of operation of elements in an array circuit are described herein. In an exemplary embodiment, a plurality of resistive elements are incorporated into an array circuit such that voltages developed across any two elements is substantially the same when an equal voltage is applied to energize the elements. In a crossbar array circuit that comprises a plurality of elements arranged in rows and columns, the resistance of each of the resistive elements is based upon a row or column to which the resistive element is connected.
