Peripheral signal handling in extensible three dimensional circuits

摘要

A method for handling peripheral signals in an extensible three dimensional circuit includes forming an extensible three dimensional circuit with a plurality of stacked crossbar arrays and at least one class of traveling lines which travel vertically and laterally through the circuit. The method also includes alternating the traveling direction of bundles of traveling lines such that there are a substantially equal number of undriven lines and underutilized lines which exit out of a given side of the circuit and creating loopback traces which connect the undriven traveling lines and the underutilized traveling lines to form driven traveling lines with a full complement of memory elements and eliminate addressing gaps within the circuit.
