A Cu atom switch fabricated with an advanced CMOS technology

Xu BAI1, Toshitsugu SAKAMOTO1, Makoto MIYAMURA1, Munehiro TADA1

NEC has been developing an FPGA using non-volatile atom switches. In the atom switch, a Cu bridge is formed or dissolved in a solid electrolyte, which leads to a very high ON/OFF conductance ratio. In this research introduction, we will show the characteristics of the Cu atom switch with scalability and low leakage current. Also, the structure of the atom-switch FPGA and its advantages of low power consumption and high speed, which are demonstrated by measuring a mapped application circuit, will be introduced.
