Improved microelectronic memory key with receptacle and systems therefor.

摘要

The key (10) contains a microelectronic circuit element, e.g., a microelectronic circuit chip or die, having an electrical lead or leads (16) exposed along the length of the key (10) for contacting electrical leads (44) in the receptacle (22) when the key is inserted therein and rotated to a "locked" position. The key (10) is particularly designed to interface with a processor and program memory system, that is, a computer.
