Abstract

PURPOSE:To simplify the read and write of information in and from a memory element by using fixed connection components. CONSTITUTION:With base 4 detached from socket 3, the circuit of electric equipment 2 is electrically insulated from memory element 1 and connecting base 4 to socket 3 supplies memory information of element 1 to the circuit of equipment 2. On the other hand, information is written in element 1, base 6 is connected to socket 3 to supply information from circuit 5 to element 1 while it is never supplied to equipment 2.
