Abstract
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.
Claims29
An electronically scannable multiplexing device comprising:
- a scanning region;
- two gates disposed at different locations relative to the scanning region;
- wherein upon application of potentials to the two gates, two depletion regions, within the scanning region, interact to generate a conducting channel within the scanning region;
- and wherein the conducting channel is controllably scannable within the scanning region by varying the potentials applied to the two gates.
