Disclosed are a compound which works as electronic materials such as a molecular memory, a molecular switch, a molecular rectifier, a molecular wire, and so on, and a molecular electronic device including the same. The swellable acrylate layer may be formed by polymerizing monomers in a composition that includes hydroxyethyl methacrylate, 2-carboxyehylacrylate, and tetra dimethacrylate. Based on the thus calculated sum, a parameter calculation circuit calculates a parameter based on which a multi-valued signal generation circuit generates a multi-valued signal. Finally, the system can include single channel memory mirror logic.
