This paper proposes three modified memristor ratioed logic (MRL) gates: NOT, NOR and A
AND (NOR B)(ie, A· B¯), each of which only needs 1 memristor and 1 NMOS. Based on the
modified MRL gates, we design some combinational logic circuits, including 1-bit
comparator, 3-bit binary encoder, 3-bit binary decoder and 4: 1 multiplexer. Furthermore, an
improved multifunctional logic module is proposed, which contains one NMOS transistor and
five memristors, and can implement AND, OR and XOR logic operations. Using this …

The traditional complementary metal oxide semiconductor (CMOS) process technology is
approaching its limits due to the continuous shrinking of current semiconductor processes,
which has implications for all aspects including device size, performance, power
consumption, etc. These aspects also create bottlenecks in traditional Von Neumann
computing architecture. As a new type of device that integrates computing and storage
functions, the memristor is thus one of the candidates for breaking the mold in the post …
