Abstract
An in-memory computing architecture is disclosed that can evaluate the transitive closure of graphs using the natural parallel flow of information in 3-D nanoscale crossbars. The architecture can be implemented using 3-D crossbar architectures with as few as two layers of 1-diode 1-resistor (1D1R) interconnects. The architecture avoids memory-processor bottlenecks and can hence scale to large graphs. The approach leads to a runtime complexity of O(n) using O(n) memristor devices. This compares favorably to conventional algorithms with a time complexity of O((n)/p+(n) log p) on p processors. The approach takes advantage of the dynamics of 3-D crossbars not available on 2-D crossbars.
