Vertical stacked type Fe-FET combinational circuit/memory for its evaluation results for non-volatile sequential circuits with BiCS technology has been newly proposed. In this scheme conventional flip flop circuit which uses more than 20 Fe-FETs has been successfully replaced by the only one Fe-FET stacked on the combinational circuit. As a result, more than X20 cost performance defined by (fabrication cost) * (cycle time for read/erase/program operation) can be successfully realized compared with that of conventional flip circuit scheme. The proposed scheme is promising candidate for realizing high cost performance non-volatile sequential circuit.
