Title:
SPIN WAVE SWITCH AND FPGA USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/038015
Kind Code:
A1
Abstract:
Provided is a compact and ultra-low power-consuming field-programmable gate array (FPGA) that makes use of a spin wave waveguide and a spin wave calculation circuit. By laminating two ferromagnetic wires on a substrate, disposing an electrode at the top of the wiring structure with an insulating film therebetween, and applying an electric field to the electrode so as to change the magnetization direction of the upper ferromagnetic wire, a spin wave switch that switches a spin wave, which propagates through one of the wires, to the other wire, is configured. A spin wave waveguide wiring network is formed using a group of the spin wave switches. A selector is configured by connecting seven information recording units, which store information according to the magnetization direction, via the spin wave waveguide, and a lookup table is formed by connecting a plurality of selectors in stages. The FPGA is configured using the spin wave waveguide wiring network and the lookup table.
