Vision and objectives

Several alternative NVM concepts are currently being explored to satisfy the need for higher storage capacity and system performance, lower power consumption, smaller form factor, lower system costs and long data-retention capability. However, a limited activity is devoted to investigating their integration and scalability.

The VERSATILE project addresses a possible integration strategy for novel memory concepts that can be arranged in two terminal devices: the crossbar architecture, where the selector and the bit storage element are vertically stacked one on top of the other and embedded between two metal electrodes. 

The main objectives of the project are:

• to develop rectifying junctions based either on II-VI, organic or hybrid organic/inorganic semiconductors, to be used as selectors in crossbar memories;
• to demonstrate the feasibility of the crossbar architecture by fabricating a 10kB memory prototype;
• to demonstrate the scalability of the rectifying junctions down to the 32 nm technology node.

Moreover, compatibility of the developed materials and processes with current CMOS technology is constantly monitored.

Project overview

The first year of the project was mainly devoted to focus the strategy and to start investigating materials and structures suitable as selectors for crossbar arrays. Activities continued in the second period to optimize the materials and start working towards the 10 Kb memory prototypes, which will be finalised in the III period along with the scalability issue.

The main achievements within the project in the first two years are: 

• the development of ZnO-based rectifying junctions with properties suitable for being integrated into crossbar arrays and for competing with the most promising 1diode-1memory integration schemes; 
• the identification by means of simulation and the synthesis of the most suitable organic materials for organic and hybrid junctions; 
• the development of an integration scheme for the fabrication of hybrid organic/inorganic junctions; 
• the definition of a process flow for the integration of crossbar into CMOS process line;
• the demonstration of compatibility with CMOS technology of organic based junctions.
