Summary:Spin torque nanodevices could be possible candidates for future architectures, they small size and low power consumption makes them a possible option for beyond Moore's law computation. Coupling of individual oscillators can be done by many different methods (e.g.: spin-wave coupling or electrical coupling). These couplings are usually static and wired for a specific array, resulting a specific functionality and it can not be changed dynamically. Coupling a large number of oscillators will require a large number of coupling elements for programmable coupling. In this paper we will show who spin torque oscillators can be coupled by common frequencies via a common coupling signal. This way a large number of oscillators can be coupled simultaneously and their coupling can be altered dynamically.
