Through the project, the two companies developed technology for forming, processing and evaluating a new ferroelectric (PZT)[3] film and created FRAM memory core process technology that is highly integrated (four times the level of conventional FRAM), features high performance (read/write speeds over three times faster than conventional FRAM) and boasts outstanding reliability (capable of more than one hundred trillion read/write cycles).
The research group used a soluble biopolymer material with a bar-like helix structure to create a ferroelectric thin film by changing inter-molecular interactions by controlling the molecular weight and molecular structure of the biopolymer.
The materials are blends of a sensing component selected from the group consisting of ferroelectric, piezoelectric, pyroelectric and photoelectric polymers and an actuating component that responds to an electric field in terms of dimensional change.
