Abstract
DISPOSITIVO GENERADOR DE REFRESCO PARA UNA MEMORIA DE ACCESO ALEATORIO DINAMICA, EN UNA INSTALACION DE TRATAMIENTO DE DATOS. COMPRENDE UNOS PRIMEROS MEDIOS LOGICOS QUE RESPONDEN A UNA SEÑAL PERIODICA DE UN CIRCUITO TEMPORIZADOR DE REFRESCO PARA GENERAR UNA SEÑAL DE PETICION DE RETENCION PARA EL PROCESADOR; SEGUNDOS MEDIOS LOGICOS QUE RESPONDEN A UNA SEÑAL DE ACOGIDA DE RETENCION DEL PROCESADOR, PARA GENERAR UNA SEÑAL DE CONTROL DE REFRESCO, TERCEROS MEDIOS LOGICOS QUE RESPONDEN A LA SEÑAL DE CONTROL DE REFRESCO PARA PROPORCIONAR UNA SEÑAL DE REFRESCO, PARA CONTROLAR EL ACCESO A LAS FILAS DE MEMORIA DE CONTROL; UN CIRCUITO CONTADOR ACOPLADO PARA INCREMENTARSE EN UNO EN RESPUESTA A CADA SEÑAL DE CONTROL DE REFRESCO; Y UN CIRCUITO SECUENCIADOR.
