Abstract

CON UN EE-PROM CON UN NUMERO DE CELULA DE MEMORIA PEQUEÑO, SE POSIBILITA UN REGISTRO INEQUIVOCO DE UN GRAN NUMERO DE ACONTECIMIENTOS, DENTRO DE QUE SE DISTRIBUYE EL ACUMULADOR A CAMPOS DE FACTORES DE CALIDAD DIFERENTES Y SE ACCIONA COMO NO CONTADOR. UNA CONEXION LOGICA POSIBILITA QUE SE ESCRIBE Y ESCOJE EL CAMPO DE ACUMULACION ELECCIONADO, Y A QUE SE ANULA EL CAMPO DE ACUMULACION CON EL FACTOR DE CALIDAD BAJO
