Abstract

LA INVENCION SE REFIERE A UN CIRCUITO SEMICONDUCTOR CON LAS SIGUIENTES CARACTERISTICAS: AL MENOS UN MODULO DE OPERACION CON UN CIRCUITO DE CONTROL Y UN MICROPROCESADOR CON MEMORIA; AL MENOS UN MODULO DE INICIALIZACION PARA PRUEBA Y/O INICIALIZACION DE LOS MODULOS DE OPERACION O PARA LOS MISMOS MODULOS DE OPERACION; AL MENOS UN MODULO DE OPERACION ESTA CONECTADO A AL MENOS UN MODULO DE INICIALIZACION POR MEDIO AL MENOS DE UN HILO (1) DE CONEXION NO INTERRUMPIDA. PARA MEJORAR LA FIABILIDAD, DESPUES DE LA CONSTRUCCION DEL CIRCUITO SEMICONDUCTOR, EL MODULO DE INICIALIZACION ESTA SEPARADO PERMANENTEMENTE CON RESPECTO AL MODULO DE OPERACION MEDIANTE CORTE DE LOS HILOS DE CONEXION. PARA HACER MAS DIFICIL LA REACTIVACION DE LOS HILOS DE CONEXION DE CORTE, EL CIRCUITO SEMICONDUCTOR TIENE LAS SIGUIENTES CARACTERISTICAS: EN EL AREA DE AL MENOS UNO DE LOS HILOS (1) DE CONEXION SE DISPONE DE UN HILO (2,3) DE POTENCIAL QUE ESTA CONECTADO AL GRUPO DE INICIALIZACION Y/O CON EL MODULO DE OPERACION; EL MODULO DE INICIALIZACION Y/O EL MODULO DE OPERACION ESTAN CONSTRUIDOS SOBRE CONEXION DEL HILO DE POTENCIAL Y AL MENOS UNO DE LOS HILOS (2,3) DE POTENCIAL CON EL HILO (1) DE CONEXION O AL MENOS UNO DE LOS HILOS DE CONEXION, QUE PUEDEN SER CONECTADOS A UN ESTADO INACTIVO.
