Description

technical field [0001] The invention relates to the technical field of electronic devices and circuits, in particular to a nanomagnetic logic majority logic gate circuit based on a magnetoelectric effect clock control method. Background technique [0002] Nanomagnet Logic (NML) uses single-domain nanomagnets to have two stable states to represent logic '0' and '1' respectively, and has the advantages of ultra-low power consumption, high integration and non-volatility. It is an important candidate for the post-CMOS era. In NML circuits, the majority logic gate is the basic logic unit, and the clock control scheme is an important part of the NML circuit. [0003] At present, there are three mainstream clock control schemes for NML circuits, which are clock control schemes based on current induction to generate an external magnetic field, clock control schemes based on spin transfer torque, and clock control schemes based on magnetoelastic properties. Among them, the clock co...

Problems solved by technology

However, this solution requires a very low aspect ratio of the nanomagnet, and many characteristics of NML depend on the aspect ratio of the nanomagnet, which will affect the performance and reliability of the NML circuit.

In addition, the clock control scheme has high requirements on the manufacturing process, which is difficult to realize under the current process conditions.
