Figure 13.23. Measured truth table for an AND gate constructed from two molecular switches
A and B 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, B= 1). The address levels listed toward the bottom
refer to the possible on (1) and off (0) arrangements of the switches A and B. [Adapted from

molecular switching devices for fiture computer technology.
