Abstract
Examples disclosed herein relate to digital hash code generation. A digital hash code generating device comprising a plurality of variable conductance elements. Each variable conductance element is coupled to a selected row line and to a selected column line of a crossbar array. Each variable conductance element comprises a conductance from a stochastic distribution of conductance. A plurality of comparator elements and each comparator element is connected to a set of at least two column lines. The plurality of comparator elements generates a hash code in response to a vector input applied to the plurality of row lines of the crossbar array.
