Outline of Final Research Achievements

A basic concept of permanent memory based on existence of a stable metal-crystal nano structure was invented together with a multilayer high-density configuration and its fabrication process. A capacitance-readout scheme to retrieve the saved data and a coding scheme to guarantee long-time readout reliability were also invented. An electro-magnetics and circuit mixed-domain design methodology was developed to integrate the nano-structure memory and the read-out circuit. A prototype was designed and fabricated. An equivalently 1,000-years long-term reliability test was conducted by using an acceleration pressure cooker. Validity of the concept and the methodology was successfully proven by the demonstration of reliable memory read-out.
