1. A two-terminal store-and-control circuit, comprising:
- a power circuit comprising only two input electrical connections, a first electrical connection for receiving a modulated first signal and a second electrical connection for receiving a second signal, wherein the power circuit provides a V+ signal and a V−
signal responsive to the modulated first signal and the second signal and the modulated first signal is a variable signal with variable periods;
a single voltage comparator for extracting a comparison signal from the modulated first signal received at the first electrical connection and the V+ signal provided by the power circuit, to produce a data signal; and
a data storage circuit connected to the V+ and V−
signals of the power circuit for receiving and storing the data signal and providing a stored data signal.

Abstract
A two-terminal store-and-control circuit includes a power circuit for receiving a modulated first signal, for receiving a second signal, for providing a power signal, and for providing a V− signal. A voltage comparator receives the modulated first signal and the V+ signal and provides a data signal that is extracted from the modulated first signal and the power signal. A data storage circuit receives and stores the data signal and provides a stored data signal. The circuit can be provided in a two-terminal store-and-control surface-mount device and employed to make a display.
