Patent ID: 7042773

Claim:
An integrated circuit for storing operating parameters, comprising: a programming circuit comprising a first input terminal to apply a control voltage, a second input terminal to apply a reference voltage and a plurality of output terminals, each output terminal of the programming circuit being configured to generate a respective programming signal; a plurality of first controllable switches; a storage circuit comprising a plurality of programming terminals, a plurality of output terminals, and a plurality of programmable elements that are selectively controlled to different settings; a plurality of second controllable switches; and a plurality of output terminals of the integrated circuit; wherein: each of the output terminals of the programming circuit are connectable, via a respective one of the first controllable switches, with a respective one of the programming terminals of the storage circuit to facilitate the generation of programming signals; each of the output terminals of the storage circuit are connectable, via a respective one of the second controllable switches, to a respective one of the output terminals of the integrated circuit; the number of programming signals generated is dependent upon the magnitude of the control voltage; and each of the programmable elements of the storage circuit is programmable to a selected setting based upon the generation of programming signals.
