In this paper, a reconfigurable LSI employing a non-volatile nanometer-scale switch, NanoBridge, is proposed, and its basic operations are demonstrated. The switch, composed of solid electrolyte copper sulfide, has a <30-nm contact diameter and <100-Ω on-resistance. Because of its small size, it can be used to create extremely dense field-programmable logic arrays. A 4 × 4 crossbar switch and a 2-input look-up-table circuit are fabricated with 0.18-μm CMOS technology, and operational tests with them have confirmed the switch's potential for use in programmable logic arrays. A 1-kb nonvolatile memory is also presented, and its potential for use as a low-voltage memory device is demonstrated.
