Abstract
Il circuito integrato incorpora mezzi resistivi o capacitivi collegati fra un primo e un secondo punto, i quali comprendono più resistori o condensatori collegati in serie fra loro e a detto primo punto, e più porte logiche collegate ciascuna da un nodo fra due adiacenti di detti resistori o condensatori a detto secondo punto, ogni porta avendo un elettrodo di comando comandabile dall'esterno del circuito integrato per aprire o chiudere la porta.Le porte logiche possono anche essere collegate ciascuna in parallelo a uno di detti resistori o condensatori, ogni porta potendo essere aperta o chiusa tramite un elettrodo di comando comandabile dall'esterno del circuito integrato.In alternativa, i resistori o condensatori possono essere collegati in parallelo fra loro; e le porte logiche sono in tal caso collegate ciascuna in serie a uno di detti resistori o condensatori.Gli elettrodi di comando delle porte logiche sono preferibilmente comandati attraverso un decodificatore incorporato nel circuito integrato.
