Memristor based 8-bit iterative full adder with space-time notation and sneak-path protection

Memristor technology is receiving an increased attention as a potential solution to meet the scaling demands in integrated circuit design. Memristor provides advantages like high-density, low-power, non-volatility and good scalability. In this paper, an 8-bit iterative full adder design is proposed that uses space-time based circuit notation. It uses stateful logic with memristive nanowire crossbar. The proposed design provides good protection against sneak-path current. The 8-bit full adder requires only 165 micro pulses to perform its operation with greatly reduced sneak-path.
