Abstract

PARA LA COMPROBACION DE LOS DATOS UTILES (N) DE UNA MEMORIA DE ESCRITURA-LECTURA (S), SE FORMAN A PARTIR DE LA CANTIDAD TOTAL DE DATOS UTILES (N) CANTIDADES PARCIALES Y PARA CADA CANTIDAD PARCIAL DE DATOS UTILES (N) SE CALCULAN DATOS DE CORRECCION DE DEFECTOS (F). LAS CANTIDADES PARCIALES DE DATOS UTILES (N) Y LOS CORRESPONDIENTES DATOS DE CORRECCION DE DEFECTOS (F) SE TRANSMITEN POR BLOQUES A LA MEMORIA DE ESCRITURA-LECTURA (S). EN LA LECTURA SE SELECCIONA CADA VEZ EL BLOQUE QUE CONTIENE LOS DATOS UTILES (N) DESEADOS Y SE COMPRUEBAN CON AYUDA DE LOS DATOS DE CORRECCION DE DEFECTOS (F).
