An electronically scannable multiplexing device is capable of addressing multiple bits within a volatile or non-volatile memory cell. The multiplexing device generates an electronically scannable conducting channel with two oppositely formed depletion regions. The depletion width of each depletion region is controlled by a voltage applied to a respective control gate at each end of the multiplexing device. The present multi-bit addressing technique allows, for example, 10 to 100 bits of data to be accessed or addressed at a single node. The present invention can also be used to build a programmable nanoscale logic array or for randomly accessing a nanoscale sensor array.
