Popis: | We developed 16 Mb 1T1R NRAM integrating CNTs resistor elements into the intermediate wirings of 55 nm CMOS. Excellent reliabilities were proven by the retention test at 150 °C extrapolated for 100 kh and the endurance test of 1E6 cycles. The switching speed was realized for cell array at 200 ns. In addition, we successfully fabricated CNTs resistor elements with 49% shrunk small via pitch cell area and realized advantageous high switching speed with 0.5 ns single pulse even omitting verify operation. |
