NEC Corp., National Institute for Materials Science, and the Japan Science and Technology Agency have announced the development of a switching technology, called NanoBridge, that migrate metal atoms in a solid electrolyte to be able to manufacture programmable LSI devices.

Already been demonstrated in a prototype circuit, the new technology uses the atom switching effect of a nanoscale metal bridge, in which an electrically conductive channel is created or annihilated by stretching a metallic bridge controlled by an electrochemical reaction inside a solid electrolyte that stabilizes the LSI wiring layer.

As a result, the operating speed of a programmable LSI device, which is indispensable for short-term equipment development, can be increased and the area of the chip reduced, thus improving performance and lowering costs in electronic appliances such as mobile equipment and digital TV receivers, according to the companies.
