Abstract
A method of making organic memory cells made of two electrodes with a controllably conductivce media between the two electrodes is disclosed. The controllably conductive media contains an organic semiconductor layer and passive layer. The organic semiconductor layer is formed using spin-on techniques with the assistance of certain solvents.
