A proposal has been written for a reviewed journal for a hybrid semiconductor and molecular chip that would have 100 billion bits per square centimeter of flash-like memory.
In this cross-section of a portion of the hypothesized hybrid micro-nano-molecular IC, a crossbar (vertical lines) is placed on top of conventional CMOS circuitry. The inset drawing shows the molecules that link the lower and upper sides of the crossbar and “mimic the behavior of a flash memory cell.”
Production cost and scalability are the key challenges. Other questions – such as reliability of the molecules –would require further specifications.
