Abstract

A static, nonvolatile, and reprogrammable programmable interconnect junction cell for implementing programmable interconnect in an integrated circuit. The programmable interconnect junction (600) is programmably configured to couple or decouple a first interconnect line (210) and a second interconnect line (220). The configured state of the programmable interconnect junction is detected directly, and memory cell detection circuitry such as sense amplifiers are not needed during normal operation. Full-rail voltages may be passed from the first interconnect line and the second interconnect line.
