AND gate address levels

Figure 13.23. Measured truth table for an AND gate constructed from two molecular switches A and 6 wired as shown at the top. The lower plot shows that there is only an output (high current) when both switches are on (A=1, S= 1). The address levels listed toward the bottom refer to the possible on (1) and off (0) arrangements of the switches A and 8. (Adapted from C. P. Collier et al., Science 285, 391 (1999).]

device can function as an AND gate. These results demonstrate the potential of molecular switching devices for future computer technology.
