Description
Summary:An improvement mechanism of the OFF-state lifetime in a complementary atom switch (CAS) is investigated by detecting a time-dependent stress voltage transition between two atom switches. The CAS consists of two bipolar-resistive-change elements connected in series with opposite direction, which are applicable for a nonvolatile crossbar switch routing signals. In the OFF-state, one switch is biased to the forward (turn-on) direction and the other to reverse (turn-off) during the crossbar switch operation. It is revealed that the switch elements do not only share the voltage stress with each other, but also mitigate the stress voltage of the forward-biased one by the reverse-biased one. The complementary sharing of the stress voltage in the two atom switches results in enlarging the OFF-state lifetime of the CAS, which is essential for keeping the crossbar switch reliability high.
