MICROELECTRONIC MEMORY KEY WITH RECEPTACLE AND SYSTEMS THEREFOR ABSTRACT This invention relates to electrical key-like devices to electrical receptacles for use in combination therewith and to electronic circuitry systems, such as computers and other operating circuits, that interface with the key-like devices through the receptacle. The keys contain a microelectronic circuit element, eg., a micro- electronic circuit chip or die, having an electrical lead or leads exposed along the length of the key for contacting electrical leads in the receptacle when the key is inserted therein and rotated to a "locked" position. The keys are particularly designed to interface with a processor and program memory system, that is, a computer.
