Abstract: A circuit comprises an array of programmable memory elements fabricated on a substrate, each memory element having one or more processable regions which, when processed by an external process in which a material is applied to at least partially cover one or more of the regions, are configured to program that memory element to one of multiple states;a first set of control lines connected to the array of memory elements, by which the contents of each individual memory element are capable of being accessed by control signals applied to a respective combination of at least two control lines in the first set of control lines;and an array of second circuit elements, different to the memory elements, each connected to a control line of the first set of control lines and to another control line of a second set of control lines, different to the first set of control lines, so as to provide access to second circuit elements in the array.
