Having a selective memory: Osmium(II)-based monolayers on glass substrates are versatile platforms for the generation of several sequential logic circuits with multiple inputs which are able to display random access memory (RAM) functionality in the form of a set/reset latch. Additionally, the type of logic displayed, for example, sequential or combinatorial, can be controlled by keeping the current state static or dynamic.
