ABSTRACT:
An electronic shift register memory (20) at the molecular level is described. The memory elements are based on a chain of electron transfer molecules (22) and the information is shifted by photoinduced (26) electron transfer reactions. The device of the invention integrates designed electronic molecules onto a VLSI substrate (36), providing an example of a "molecular electronic device" which may be fabricated.
