A new multi-state molecular building block for tomorrows electric circuits and memory storage devices was realized. Information technology is the core of many industries today. The main challenge facing this industry is the need for miniaturization, due to an ever increase in information density. Molecular information processing and storage is becoming a logical candidate to replace the available methods, by use of molecules as building blocks for bottom up approaches. A memory device that exists in multiple stable states with a molecular based assembly was prepared. This can offer new ways in which information is processed (multiple-threads) as well as increasing the information density in random access memory (RAM), storage devices and methods.

- Increase in information density, with no need for additional spatial requirements.
- Alternative to silicon technology
Electronically addressable multi-state memory for sequential logic flip-flop, flip-flap-flop circuits, and higher order switchable memory circuits, can be constructed by materials composed of a molecular based assembly that can exist in multiple states. Since the optical output is a precise function of the applied voltage, multi-valued information can be written on to the assembly by applying specific potential biases. The read and write cycle is completed by monitoring the induced optical changes of the system. This system uses the same electrical inputs as conventional memory devices and uses an optical read-out which is non destructive and fast. The properties of the device can be used to create an apparatus for information storage especially with respect to developing solid-state drives in computers (SSDs).
